| ./docs/contributing/Building, Debugging, and Testing on Unix.md | # Building, Debugging and Testing on Unix
This guide is meant to help developers setup an environment for debugging / contributing to Roslyn from Linux.
Particularly for developers who aren't experienced with .NET Core development on Linux.
## Working with the code
1. Ensure the commands `git` and `curl` are available
1. Clone [email protected]:dotnet/roslyn.git
1. Run `./build.sh --restore`
1. Run `./build.sh --build`
## Working in Visual Studio Code
1. Install [VS Code](https://code.visualstudio.com/Download)
- After you install VS Code, install the [C# extension](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp)
- Important tip: You can look up editor commands by name by hitting *Ctrl+Shift+P*, or by hitting *Ctrl+P* and typing a `>` character. This will help you get familiar with editor commands mentioned below. On a Mac, use *⌘* instead of *Ctrl*.
2. Install a recent preview [.NET Core SDK](https://dotnet.microsoft.com/download/dotnet-core). At time of writing, Roslyn uses .NET 5 preview 8. The exact version in use is recorded in our [global.json](https://github.com/dotnet/roslyn/blob/main/global.json) file.
3. You can build from VS Code by running the *Run Build Task* command, then selecting an appropriate task such as *build* or *build current project* (the latter builds the containing project for the current file you're viewing in the editor).
4. You can run tests from VS Code by opening a test class in the editor, then using the *Run Tests in Context* and *Debug Tests in Context* editor commands. You may want to bind these commands to keyboard shortcuts that match their Visual Studio equivalents (**Ctrl+R, T** for *Run Tests in Context* and **Ctrl+R, Ctrl+T** for *Debug Tests in Context*).
## Running Tests
The unit tests can be executed by running `./build.sh --test`.
To run all tests in a single project, it's recommended to use the `dotnet test path/to/project` command.
## GitHub
The best way to clone and push is to use SSH. On Windows you typically use HTTPS and this is not directly compatible
with two factor authentication (requires a PAT). The SSH setup is much simpler and GitHub has a great HOWTO for
getting this setup.
https://help.github.com/articles/connecting-to-github-with-ssh/
## Debugging test failures
The best way to debug is using lldb with the SOS plugin. This is the same SOS as used in WinDbg and if you're familiar
with it then lldb debugging will be pretty straight forward.
The [dotnet/diagnostics](https://github.com/dotnet/diagnostics) repo has more information:
- [Getting LLDB](https://github.com/dotnet/diagnostics/blob/main/documentation/lldb/linux-instructions.md)
- [Installing SOS](https://github.com/dotnet/diagnostics/blob/main/documentation/installing-sos-instructions.md)
- [Using SOS](https://github.com/dotnet/diagnostics/blob/main/documentation/sos-debugging-extension.md)
CoreCLR also has some guidelines for specific Linux debugging scenarios:
- https://github.com/dotnet/coreclr/blob/main/Documentation/botr/xplat-minidump-generation.md
- https://github.com/dotnet/coreclr/blob/main/Documentation/building/debugging-instructions.md#debugging-core-dumps-with-lldb.
Corrections:
- LLDB and createdump must be run as root
- `dotnet tool install -g dotnet-symbol` must be run from `$HOME`
### Core Dumps
The CoreClr does not used the standard core dumping mechanisms on Linux. Instead you must specify via
environment variables that you want a core dump to be produced. The simplest setup is to do the following:
```
> export COMPlus_DbgEnableMiniDump=1
> export COMPlus_DbgMiniDumpType=4
```
This will cause full memory dumps to be produced which can then be loaded into LLDB.
A preview of [dotnet-dump](https://github.com/dotnet/diagnostics/blob/main/documentation/dotnet-dump-instructions.md) is also available for interactively creating and analyzing dumps.
### GC stress failures
When you suspect there is a GC failure related to your test then you can use the following environment variables
to help track it down.
```
> export COMPlus_HeapVerify=1
> export COMPlus_gcConcurrent=1
```
The `COMPlus_HeapVerify` variable causes GC to run a verification routine on every entry and exit. Will crash with
a more actionable trace for the GC team.
The `COMPlus_gcConcurrent` variable removes concurrency in the GC. This helps isolate whether this is a GC failure
or memory corruption outside the GC. This should be set after you use `COMPLUS_HeapVerify` to determine it is
indeed crashing in the GC.
Note: this variables can also be used on Windows as well.
## Ubuntu 18.04
The recommended OS for developing Roslyn is Ubuntu 18.04. This guide was written using Ubuntu 18.04 but should be
applicable to most Linux environments. Ubuntu 18.04 was chosen here due to it's support for enhanced VMs in Hyper-V.
This makes it easier to use from a Windows machine: full screen, copy / paste, etc ...
### Hyper-V
Hyper-V has a builtin Ubuntu 18.04 image which supports enhanced mode. Here is a tutorial for creating
such an image:
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/quick-create-virtual-machine
When following this make sure to:
1. Click Installation Source and uncheck "Windows Secure Boot"
1. Complete the Ubuntu installation wizard. Full screen mode won't be available until this is done.
Overall this takes about 5-10 minutes to complete.
### Source Link
Many of the repositories that need to be built use source link and it crashes on Ubuntu 18.04 due to dependency changes.
To disable source link add the following to the `Directory.Build.props` file in the root of the repository.
``` xml
<EnableSourceControlManagerQueries>false</EnableSourceControlManagerQueries>
<EnableSourceLink>false</EnableSourceLink>
<DeterministicSourcePaths>false</DeterministicSourcePaths>
```
### Prerequisites
Make sure to install the following via `apt install`
- clang
- lldb
- cmake
- xrdp
| # Building, Debugging and Testing on Unix
This guide is meant to help developers setup an environment for debugging / contributing to Roslyn from Linux.
Particularly for developers who aren't experienced with .NET Core development on Linux.
## Working with the code
1. Ensure the commands `git` and `curl` are available
1. Clone [email protected]:dotnet/roslyn.git
1. Run `./build.sh --restore`
1. Run `./build.sh --build`
## Working in Visual Studio Code
1. Install [VS Code](https://code.visualstudio.com/Download)
- After you install VS Code, install the [C# extension](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp)
- Important tip: You can look up editor commands by name by hitting *Ctrl+Shift+P*, or by hitting *Ctrl+P* and typing a `>` character. This will help you get familiar with editor commands mentioned below. On a Mac, use *⌘* instead of *Ctrl*.
2. Install the [.NET 6.0 RC 1 SDK](https://dotnet.microsoft.com/download/dotnet-core/6.0).
3. You can build from VS Code by running the *Run Build Task* command, then selecting an appropriate task such as *build* or *build current project* (the latter builds the containing project for the current file you're viewing in the editor).
4. You can run tests from VS Code by opening a test class in the editor, then using the *Run Tests in Context* and *Debug Tests in Context* editor commands. You may want to bind these commands to keyboard shortcuts that match their Visual Studio equivalents (**Ctrl+R, T** for *Run Tests in Context* and **Ctrl+R, Ctrl+T** for *Debug Tests in Context*).
## Running Tests
The unit tests can be executed by running `./build.sh --test`.
To run all tests in a single project, it's recommended to use the `dotnet test path/to/project` command.
## GitHub
The best way to clone and push is to use SSH. On Windows you typically use HTTPS and this is not directly compatible

| ./docs/contributing/Building, Debugging, and Testing on Windows.md | # Building, Debugging and Testing on Windows
## Working with the code
Using the command line, Roslyn can be developed using the following pattern:
1. Clone https://github.com/dotnet/roslyn
1. Run Restore.cmd
1. Run Build.cmd
1. Run Test.cmd
## Recommended version of .NET Framework
The minimal required version of .NET Framework is 4.7.2.
## Developing with Visual Studio 2022
1. [Visual Studio 2022 17.0 Preview](https://visualstudio.microsoft.com/vs/preview/vs2022/)
- Ensure C#, VB, MSBuild, .NET Core and Visual Studio Extensibility are included in the selected work loads
- Ensure Visual Studio is on Version "17.0" or greater
- Ensure "Use previews of the .NET Core SDK" is checked in Tools -> Options -> Environment -> Preview Features
- Restart Visual Studio
1. [.NET 6.0 Preview 7 SDK](https://dotnet.microsoft.com/download/dotnet-core/6.0) [Windows x64 installer](https://dotnet.microsoft.com/download/dotnet/thank-you/sdk-6.0.100-preview.7-windows-x64-installer)
1. [PowerShell 5.0 or newer](https://docs.microsoft.com/en-us/powershell/scripting/setup/installing-windows-powershell). If you are on Windows 10, you are fine; you'll only need to upgrade if you're on earlier versions of Windows. The download link is under the ["Upgrading existing Windows PowerShell"](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-windows-powershell?view=powershell-6#upgrading-existing-windows-powershell) heading.
1. Run Restore.cmd
1. Open Roslyn.sln
## Developing with Visual Studio Code
See the [Building, Debugging, and Testing on Unix](Building,%20Debugging,%20and%20Testing%20on%20Unix.md#working-in-visual-studio-code) documentation to get started developing Roslyn using Visual Studio Code.
## Running Tests
There are a number of options for running the core Roslyn unit tests:
### Command Line
The Test.cmd script will run our unit test on already built binaries. It can be passed the `-build` argument to force a new build before running tests.
1. Run the "Developer Command Prompt for VS2022" from your start menu.
2. Navigate to the directory of your Git clone.
3. Run `Test.cmd` in the command prompt.
You can more precisely control how the tests are run by running the eng/build.ps1 script directly with the relevant options. For example passing in the `-test` switch will run the tests on .NET Framework, whilst passing in the `-testCoreClr` switch will run the tests on .NET Core.
The results of the tests can be viewed in the artifacts/TestResults directory.
### Test Explorer
Tests can be run and debugged from the Test Explorer window. For best performance, we recommend the following:
1. Open **Tools → Options... → Test**
1. Check the box for **Discover tests in real time from source files**
2. Uncheck the box for **Additionally discover tests from build assemblies...**
2. Use the Search box of Test Explorer to narrow the scope of visible tests to the feature(s) you are working on
3. When you are not actively running tests, set the search query to `__NonExistent__` to hide all tests from the UI
### WPF Test Runner
To debug through tests, you can right click the test project that contains your
tests and choose **Set as Startup Project**. Then press F5. This will run the
tests under the command line runner. Some members of the team have been
working on a GUI runner that allows selection of individual tests, etc. Grab
the source from
[xunit.runner.wpf](https://github.com/pilchie/xunit.runner.wpf), build it and
give it a try.
## Trying Your Changes in Visual Studio
### Deploying with F5
The Rosyln solution is designed to support easy debugging via F5. Several of our
projects produce VSIX which deploy into Visual Studio during build. The F5 operation
will start a new Visual Studio instance using those VSIX which override our installed
binaries. This means trying out a change to the language, IDE or debugger is as
simple as hitting F5. Note that for changes to the compiler, out-of-process builds won't use the privately built version of the compiler.
The startup project needs to be set to `RoslynDeployment`. This should be
the default but in some cases will need to be set explicitly.
Here are what is deployed with each extension, by project that builds it. If
you're working on a particular area, you probably want to set the appropriate
project as your startup project to optimize building and deploying only the relevant bits.
- **Roslyn.VisualStudio.Setup**: this project can be found inside the VisualStudio folder
from the Solution Explorer, and builds Roslyn.VisualStudio.Setup.vsix. It
contains the core language services that provide C# and VB editing. It also
contains the copy of the compiler that is used to drive IntelliSense and
semantic analysis in Visual Studio. Although this is the copy of the compiler
that's used to generate squiggles and other information, it's not the
compiler used to actually produce your final .exe or .dll when you do a
build. If you're working on fixing an IDE bug, this is the project you want
to use.
- **Roslyn.VisualStudio.InteractiveComponents**: this project can be found in the
Interactive\Setup folder from the Solution Explorer, and builds
Roslyn.VisualStudio.InteractiveComponents.vsix.
- **Roslyn.Compilers.Extension**: this project can be found inside the Compilers\Packages folder
from the Solution Explorer, and builds Roslyn.Compilers.Extension.vsix.
This deploys a copy of the command line compilers that are used to do actual
builds in the IDE. It only affects builds triggered from the Visual Studio
experimental instance it's installed into, so it won't affect your regular
builds. Note that if you install just this, the IDE won't know about any
language features included in your build. If you're regularly working on new
language features, you may wish to consider building both the
CompilerExtension and VisualStudioSetup projects to ensure the real build and
live analysis are synchronized.
- **ExpressionEvaluatorPackage**: this project can be found inside the
ExpressionEvaluator\Setup folder from the Solution Explorer, and builds
ExpressionEvaluatorPackage.vsix. This deploys the expression evaluator and
result providers, the components that are used by the debugger to parse and
evaluate C# and VB expressions in the Watch window, Immediate window, and
more. These components are only used when debugging.
The experimental instance used by Roslyn is an entirely separate instance of
Visual Studio with it's own settings and installed extensions. It's also, by
default, a separate instance than the standard "Experimental Instance" used by
other Visual Studio SDK projects. If you're familiar with the idea of Visual
Studio hives, we deploy into the RoslynDev root suffix.
### Deploying with VSIX and Nuget package
If you want to try your extension in your day-to-day use of Visual Studio, you
can find the extensions you built in your Binaries folder with the .vsix
extension. You can double-click the extension to install it into your main
Visual Studio hive. This will replace the base installed version. Once it's
installed, you'll see it marked as "Experimental" in Tools > Extensions and
Updates to indicate you're running your experimental version. You can uninstall
your version and go back to the originally installed version by choosing your
version and clicking Uninstall.
If you only install the VSIX, then the IDE will behave correctly (ie. new compiler
and IDE behavior), but the Build operation or building from the command-line won't.
To fix that, add a reference to the `Microsoft.Net.Compilers.Toolset` you built into
your csproj. As shown below, you'll want to (1) add a nuget source pointing to your local build folder,
(2) add the package reference, then (3) verify the Build Output of your project with a
`#error version` included in your program.
### Deploying with command-line
You can build and deploy with the following command:
`.\Build.cmd -Configuration Release -deployExtensions -launch`.
Then you can launch the `RoslynDev` hive with `devenv /rootSuffix RoslynDev`.
### Referencing bootstrap compiler
If you made changes to a Roslyn compiler and want to build any projects with it, you can either
use the Visual Studio hive where your **CompilerExtension** is installed, or from
command line, run msbuild with `/p:BootstrapBuildPath=YourBootstrapBuildPath`.
`YourBootstrapBuildPath` could be any directory on your machine so long as it had
csc and vbc inside it. You can check the cibuild.cmd and see how it is used.
### Troubleshooting your setup
To confirm what version of the compiler is being used, include `#error version` in your program
and the compiler will produce a diagnostic including its own version as well as the language
version it is operating under.
You can also attach a debugger to Visual Studio and check the loaded modules, looking at the folder
where the various `CodeAnalysis` modules were loaded from (the `RoslynDev` should load them somewhere
under `AppData`, not from `Program File`).
### Testing on the [dotnet/runtime](https://github.com/dotnet/runtime) repo
1. make sure that you can build the `runtime` repo as baseline (run `build.cmd libs`, which should be sufficient to build all C# code, installing any prerequisites if prompted to)
2. `build.cmd -pack` on your `roslyn` repo
3. in `%userprofile%\.nuget\packages\microsoft.net.compilers.toolset` delete the version of the toolset that you just packed so that the new one will get put into the cache
4. modify your local enlistment of `runtime` as illustrated in [this commit](https://github.com/RikkiGibson/runtime/commit/da3c6d96c3764e571269b07650a374678b476384) then build again
- add `<RestoreAdditionalProjectSources><PATH-TO-YOUR-ROSLYN-ENLISTMENT>\artifacts\packages\Debug\Shipping\</RestoreAdditionalProjectSources>` using the local path to your `roslyn` repo to `Directory.Build.props`
- add `<MicrosoftNetCompilersToolsetVersion>3.9.0-dev</MicrosoftNetCompilersToolsetVersion>` with the package version you just packed (look in above artifacts folder) to `eng/Versions.props`
### Testing with extra IOperation validation
Run `build.cmd -testIOperation` which sets the `ROSLYN_TEST_IOPERATION` environment variable to `true` and runs the tests.
For running those tests in an IDE, the easiest is to find the `//#define ROSLYN_TEST_IOPERATION` directive and uncomment it.
See more details in the [IOperation test hook](https://github.com/dotnet/roslyn/blob/main/docs/compilers/IOperation%20Test%20Hook.md) doc.

default, a separate instance than the standard "Experimental Instance" used by
other Visual Studio SDK projects. If you're familiar with the idea of Visual
Studio hives, we deploy into the RoslynDev root suffix.
### Deploying with VSIX and Nuget package
If you want to try your extension in your day-to-day use of Visual Studio, you
can find the extensions you built in your Binaries folder with the .vsix
extension. You can double-click the extension to install it into your main
Visual Studio hive. This will replace the base installed version. Once it's
installed, you'll see it marked as "Experimental" in Tools > Extensions and
Updates to indicate you're running your experimental version. You can uninstall
your version and go back to the originally installed version by choosing your
version and clicking Uninstall.
If you only install the VSIX, then the IDE will behave correctly (ie. new compiler
and IDE behavior), but the Build operation or building from the command-line won't.
To fix that, add a reference to the `Microsoft.Net.Compilers.Toolset` you built into
your csproj. As shown below, you'll want to (1) add a nuget source pointing to your local build folder,
(2) add the package reference, then (3) verify the Build Output of your project with a
`#error version` included in your program.
### Deploying with command-line
You can build and deploy with the following command:
`.\Build.cmd -Configuration Release -deployExtensions -launch`.
Then you can launch the `RoslynDev` hive with `devenv /rootSuffix RoslynDev`.
### Referencing bootstrap compiler
If you made changes to a Roslyn compiler and want to build any projects with it, you can either
use the Visual Studio hive where your **CompilerExtension** is installed, or from
command line, run msbuild with `/p:BootstrapBuildPath=YourBootstrapBuildPath`.
`YourBootstrapBuildPath` could be any directory on your machine so long as it had
csc and vbc inside it. You can check the cibuild.cmd and see how it is used.
### Troubleshooting your setup
To confirm what version of the compiler is being used, include `#error version` in your program
and the compiler will produce a diagnostic including its own version as well as the language
version it is operating under.
You can also attach a debugger to Visual Studio and check the loaded modules, looking at the folder
where the various `CodeAnalysis` modules were loaded from (the `RoslynDev` should load them somewhere
under `AppData`, not from `Program File`).
### Testing on the [dotnet/runtime](https://github.com/dotnet/runtime) repo
1. make sure that you can build the `runtime` repo as baseline (run `build.cmd libs`, which should be sufficient to build all C# code, installing any prerequisites if prompted to)
2. `build.cmd -pack` on your `roslyn` repo
3. in `%userprofile%\.nuget\packages\microsoft.net.compilers.toolset` delete the version of the toolset that you just packed so that the new one will get put into the cache
4. modify your local enlistment of `runtime` as illustrated in [this commit](https://github.com/RikkiGibson/runtime/commit/da3c6d96c3764e571269b07650a374678b476384) then build again
- add `<RestoreAdditionalProjectSources><PATH-TO-YOUR-ROSLYN-ENLISTMENT>\artifacts\packages\Debug\Shipping\</RestoreAdditionalProjectSources>` using the local path to your `roslyn` repo to `Directory.Build.props`
- add `<MicrosoftNetCompilersToolsetVersion>3.9.0-dev</MicrosoftNetCompilersToolsetVersion>` with the package version you just packed (look in above artifacts folder) to `eng/Versions.props`
### Testing with extra IOperation validation
Run `build.cmd -testIOperation` which sets the `ROSLYN_TEST_IOPERATION` environment variable to `true` and runs the tests.
For running those tests in an IDE, the easiest is to find the `//#define ROSLYN_TEST_IOPERATION` directive and uncomment it.
See more details in the [IOperation test hook](https://github.com/dotnet/roslyn/blob/main/docs/compilers/IOperation%20Test%20Hook.md) doc.

# This is intended to replace the pattern of manually copy-pasting a command, wrapping it in quotes,
# and printing it using "Write-Host". The copy-paste method is more readable in build logs, but less
# maintainable and less reliable. It is easy to make a mistake and modify the command without
# properly updating the "Write-Host" line, resulting in misleading build logs. The probability of
# this mistake makes the pattern hard to trust when it shows up in build logs. Finding the bug in
# existing source code can also be difficult, because the strings are not aligned to each other and
# the line may be 300+ columns long.
#
# By removing the need to maintain two copies of the command, Exec-BlockVerbosely avoids the issues.
#
# In Bash (or any posix-like shell), "set -x" prints usable verbose output automatically.
# "Set-PSDebug" appears to be similar at first glance, but unfortunately, it isn't very useful: it
# doesn't print any info about the variables being used by the command, which is normally the

// The portion of the overload resolution spec quoted above is subtle and somewhat
// controversial. The upshot of this is that overload resolution does not consider
// constraints to be a part of the signature. Overload resolution matches arguments to
// parameter lists; it does not consider things which are outside of the parameter list.
// If the best match from the arguments to the formal parameters is not viable then we
// give an error rather than falling back to a worse match.
//
// Consider the following:
//
// void M<T>(T t) where T : Reptile {}
// void M(object x) {}
// ...
// M(new Giraffe());
//
// The correct analysis is to determine that the applicable candidates are
// M<Giraffe>(Giraffe) and M(object). Overload resolution then chooses the former
// because it is an exact match, over the latter which is an inexact match. Only after
// the best method is determined do we check the constraints and discover that the
// constraint on T has been violated.
//
// Note that this is different from the rule that says that during type inference, if an
// inference violates a constraint then inference fails. For example:
//
// class C<T> where T : struct {}
// ...
// void M<U>(U u, C<U> c){}
// void M(object x, object y) {}
// ...
// M("hello", null);
//
// Type inference determines that U is string, but since C<string> is not a valid type
// because of the constraint, type inference fails. M<string> is never added to the
// applicable candidate set, so the applicable candidate set consists solely of
// M(object, object) and is therefore the best match.

// SPEC: declared on the generic method. If any type argument does not satisfy the corresponding constraint(s) on
// SPEC: the type parameter, a binding-time error occurs.
// The portion of the overload resolution spec quoted above is subtle and somewhat
// controversial. The upshot of this is that overload resolution does not consider
// constraints to be a part of the signature. Overload resolution matches arguments to
// parameter lists; it does not consider things which are outside of the parameter list.
// If the best match from the arguments to the formal parameters is not viable then we
// give an error rather than falling back to a worse match.
//
// Consider the following:
//
// void M<T>(T t) where T : Reptile {}
// void M(object x) {}
// ...
// M(new Giraffe());
//
// The correct analysis is to determine that the applicable candidates are
// M<Giraffe>(Giraffe) and M(object). Overload resolution then chooses the former
// because it is an exact match, over the latter which is an inexact match. Only after
// the best method is determined do we check the constraints and discover that the
// constraint on T has been violated.
//
// Note that this is different from the rule that says that during type inference, if an
// inference violates a constraint then inference fails. For example:
//
// class C<T> where T : struct {}
// ...
// void M<U>(U u, C<U> c){}
// void M(object x, object y) {}
// ...
// M("hello", null);
//
// Type inference determines that U is string, but since C<string> is not a valid type
// because of the constraint, type inference fails. M<string> is never added to the
// applicable candidate set, so the applicable candidate set consists solely of
// M(object, object) and is therefore the best match.

{
// This gets a bit complicated. Let's break it down.
//
// First off, let's assume that the "other" assembly is GrantingAssembly.DLL, that the "this"
// assembly is "WantingAssembly.DLL", and that GrantingAssembly has named WantingAssembly as a friend (that is a precondition
// to calling this method). Whether we allow WantingAssembly to see internals of GrantingAssembly depends on these four factors:
//
// q1) Is GrantingAssembly strong-named?
// q2) Did GrantingAssembly name WantingAssembly as a friend via a strong name?
// q3) Is WantingAssembly strong-named?
// q4) Does GrantingAssembly give a strong-name for WantingAssembly that matches our strong name?
//
// Before we dive into the details, we should mention two additional facts:
//
// * If the answer to q1 is "yes", and GrantingAssembly was compiled by a Roslyn compiler, then q2 must be "yes" also.
// Strong-named GrantingAssembly must only be friends with strong-named WantingAssembly. See the blog article
// http://blogs.msdn.com/b/ericlippert/archive/2009/06/04/alas-smith-and-jones.aspx
// for an explanation of why this feature is desirable.
//
// Now, just because the compiler enforces this rule does not mean that we will never run into
// a scenario where GrantingAssembly is strong-named and names WantingAssembly via a weak name. Not all assemblies
// were compiled with a Roslyn compiler. We still need to deal sensibly with this situation.
// We do so by ignoring the problem; if strong-named GrantingAssembly extends friendship to weak-named
// WantingAssembly then we're done; any assembly named WantingAssembly is a friend of GrantingAssembly.

// This gets a bit complicated. Let's break it down.
//
// First off, let's assume that the "other" assembly is GrantingAssembly.DLL, that the "this"
// assembly is "WantingAssembly.DLL", and that GrantingAssembly has named WantingAssembly as a friend (that is a precondition
// to calling this method). Whether we allow WantingAssembly to see internals of GrantingAssembly depends on these four factors:
//
// q1) Is GrantingAssembly strong-named?
// q2) Did GrantingAssembly name WantingAssembly as a friend via a strong name?
// q3) Is WantingAssembly strong-named?
// q4) Does GrantingAssembly give a strong-name for WantingAssembly that matches our strong name?
//
// Before we dive into the details, we should mention two additional facts:
//
// * If the answer to q1 is "yes", and GrantingAssembly was compiled by a Roslyn compiler, then q2 must be "yes" also.
// Strong-named GrantingAssembly must only be friends with strong-named WantingAssembly. See the blog article
// http://blogs.msdn.com/b/ericlippert/archive/2009/06/04/alas-smith-and-jones.aspx
// for an explanation of why this feature is desirable.
//
// Now, just because the compiler enforces this rule does not mean that we will never run into
// a scenario where GrantingAssembly is strong-named and names WantingAssembly via a weak name. Not all assemblies
// were compiled with a Roslyn compiler. We still need to deal sensibly with this situation.
// We do so by ignoring the problem; if strong-named GrantingAssembly extends friendship to weak-named
// WantingAssembly then we're done; any assembly named WantingAssembly is a friend of GrantingAssembly.
//
// Incidentally, the C# compiler produces error CS1726, ERR_FriendAssemblySNReq, and VB produces
// the error VB31535, ERR_FriendAssemblyStrongNameRequired, when compiling
// a strong-named GrantingAssembly that names a weak-named WantingAssembly as its friend.
//
// * If the answer to q1 is "no" and the answer to q3 is "yes" then we are in a situation where
// strong-named WantingAssembly is referencing weak-named GrantingAssembly, which is illegal. In the dev10 compiler
