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.
