CsWin32: Generator may fail with "Could not load file or assembly 'YamlDotNet..."

Currently for some reason the source generator starts to bail out when it sees GetCurrentProcess when called inside of dotnet build.

Oddly it seems to generate just fine from within Visual Studio even if I use the .NET 6 Preview 1/2 SDK’s.

This happens with my project with the following NativeMethods.txt:

GetCurrentProcess
GetCurrentProcessId
GetCurrentThreadId
MiniDumpWriteDump

The first 2 is used when calling MiniDumpWriteDump and the 3rd one is for when constructing the EXCEPTION_INFORMATION structure for the call.

and the following NativeMethods.json file:

{
  "$schema": "https://raw.githubusercontent.com/microsoft/CsWin32/main/src/Microsoft.Windows.CsWin32/settings.schema.json",
  "allowMarshaling": false
}

Ok, I have simplified the reproducibility of this issue down to clone git clone https://github.com/Elskom/Sdk.git --recursive --branch use-sourcegenerators followed by a build dotnet build --configuration Release 😂.

Also, I use the default one now, even with non default it still would get this error, and I tried every build of CsWin32 that was released to nuget.org with the same issue.

I use the .NET 6 SDK but on that project I target netstandard2.0, due to also needing to have the same build work with net461+, .net core 2.0+, and anything else that implement .NET Standard 2.0+.

Is that this issue? https://github.com/dotnet/roslyn/issues/52177

Here is what I heard back from the Roslyn team:

Essentially the build works when you use msbuild but not “dotnet build”. The latter is happening on .NET Core and we don’t fully isolate anaylzers in independent ALC yet. It’s on the backlog for Dev17 / C# 10.

AArnott on May 25, 2021

I am concerned however at the lack of isolation between analyzers that the C# compiler IMO ought to be providing so that one analyzer’s dependencies does not cause problems for another’s dependencies. I’ll follow up with the Roslyn team on this.

Hey @AArnott, I’m interested in hearing what is the take of the Roslyn team on it. Is there a link? Is it public issue?
