I'm fine with this, but would like @jasonmalinowski to take a look as well.

You may want to make a note that this was mono specific, lest somebody tries to undo this change being confused why it works on other platforms.

Sure, I've updated the comment now.

I filed #74407 to look at what it'd take to get our tests running on mono to catch issues like this. |

The LoadProjectFileAsync routine calls EnsureMSBuildLoaded to make sure the Microsoft.Build.dll is accessible, but requires types from that assembly within the routine itself. This may not always work with Mono, as the JIT may look up the types during compilation. Fixed by splitting out a LoadProjectFileCoreAsync routine, similarly to what is already done for GetProjectsInSolution. Fixes dotnet/runtime#101121.

Not sure why this is failing now after just a comment change ... seems an infrastructure issue. |

I wanted to run the roslyn test suite on Linux on arm64. Building
everything worked, but running tests would fail with errors like:
Errors Microsoft.CodeAnalysis.CSharp.Emit.UnitTests_1
Could not find 'dotnet' host for the 'X64' architecture.
You can resolve the problem by installing the 'X64' .NET.
With the changes in this commit, I can build and run all tests using:
$ ./eng/build.sh --restore --build --pack
$ ./eng/build.sh --test
I would, eventually, like to be able to run the tests on other
platforms, including s390x and ppc64le. Hopefully that might help
identify/fix issues like dotnet#74392
earlier.
One thing I am not too happy about in this change is how many places
need an explicit addition of "linux-arm64". That won't scale as we want
to add more architectures.

The test run failed. Think it's still using stale integration test bits. Worry that this PR may be snagged on stale state. I rebased locally, pushed to a new branch and opened a new PR. Hopefully that one will get past these issues #74994. |
|
Closing as I got this change to merge in cleanly in #74994. Sorry for losing track of this. |
