This issue is moved from fsharp/fsharp#668 .

Some FSharpType and FSharpValue methods are defined by F# Type Extensions.
However, C# can not access F# Type Extensions.
And Some methods are not defined in .NET Core( https://github.com/fsharp/fsharp/blob/4.1.0.0/src/fsharp/FSharp.Core/reflect.fsi#L266 ).

Repro steps

  1. dotnet new classlib -lang C# and add <PackageReference Include="FSharp.Core" Version="4.1.0" />.

  2. Call Microsoft.FSharp.Reflection.FSharpType.IsRecord

Expected behavior

Build succeeded.

Actual behavior

error CS0117: 'FSharpType' does not contain a definition for 'IsRecord'

Workaround(s)

These methods can call via reflection(e.g. https://github.com/pocketberserker/FSharpNETCoreSandbox/blob/443c35362cbdd167e59ffea03c535fbc251b212e/CsNETCore/Sandbox.cs#L11 ).
