Please provide a succinct description of the issue.

MethodAccessException on equality comparison of a record with private fields but only when building from visual studio (17.11.5).
This is (probably) somehow related to this issue #17447
The SDK should be pinned at 8.0.300 by the global.json file, this version should not have this problem I believe.

Provide the steps required to reproduce the problem:

Currently installed sdks and runtimes:

  1. Execute Console.exe (from the command line).

Expected behavior

@ main$ Console/bin/Debug/net8.0/Console.exe
Comparing two values from a defined in a referenced library with a private constructor.
Not equal

Actual behavior

Comparing two values from a defined in a referenced library with a private constructor.
Unhandled exception. System.MethodAccessException: Attempt by method 'Program.main(System.String[])' to access method 'LibA+TypeWithPrivateConstructor.Equals(TypeWithPrivateConstructor, System.Collections.IEqualityComparer)' failed.
   at Program.main(String[] _arg1) in D:\git\equals\Console\Program.fs:line 9

Known workarounds

  1. Build from command line dotnet build equals.sln.

Now it simply runs as expected.

Related information

I added the following log target to the project files:

  <Target Name="WhichSDK" BeforeTargets="Build" >
    <Message Importance="high" Text="$(MSBuildProjectName): using .NET Core SDK: $(NETCoreSdkVersion)" />
  </Target>

Which prints the expected 8.0.300 SDK version. Both when building from Visual Studio or from the CLI.

Additionally the installed sdks/runtimes:

Any pointer as to what could cause this or how to further investigate?

I just tried installing visual studio preview 17.12.0 preview 4.0.
When building from within this VS version I do get the expected output and do not hit the bug.

It seems that somehow VS 17.11.5 is using the wrong SDK version?

Yeah, it's the same issue and was fixed in the later VS

What I don’t understand is that it should build using the SDK indicated by ‘global.json’ right?

It should, yes, but it might theoretically pick different locations for compiler itself (shipped with VS vs standalone) as well as different compilers (desktop/coreclr), it's currently hard to say what compiler was picked up for which version without binlog, we have quite complex logic for that.

I think for me personally I can work around this until the next VS release, however if I can help by providing additional information I am happy to do so.

I followed https://github.com/dotnet/project-system-tools?tab=readme-ov-file#getting-higher-fidelity-logs-from-vs-vs2022-onwards
and performed a build of the reproduction project to obtain a binlog.

Not sure which of these files are interesting (and how to best share them here 😄) ?

You can share them via email probably, sending to fsharp[at]microsoft.com, so we can look into it when we'll get to it. Thanks in advance!

Consider creating a ticket on VS developer community - you can upload them privately there and the team can access them.
