ParseAndCheckFileInProject fails

[auduchinok]

Running FSharpChecker.ParseAndCheckFileInProject fails with creation error returned:

Could not load file or assembly 'Microsoft.Build.Utilities.Core, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

It happens due to extra FCS dependencies were added in #9870: https://github.com/dotnet/fsharp/pull/9870/files#diff-f80f13c95d4e5cb2e376c9f82051683af78316220d065db8470e4894b096c46fR731-R733

Removing the references (and moving the related code to #if makes it work as expected (since the moved declarations aren't used in netsandard2.0 FCS anyway).

I believe FCS should not depend on MSBuild directly like this, since it quite constraints the environment FCS could be used in.

I'm hitting this failure as well when updating FSHarp.Formatting to use latest FCS

I agree

@baronfel Have you noticed this issue with people using latest FCS?

[baronfel]

Yes, many consumers have had to add this package (including things like sharplab and xunit).

We've had to workaround it by temporarily deleting the references and related code in our FCS build.

I take it this still an issue with FCS 38.0.2? I don't think we can get rid of the dependency but it should at least be added to the nuspec.

Closing out older issue due to needs more info
