Cann't open .fs files in MonoDevelop 2.4.2

[o01eg]

When I try to open .fs files from F# projects I get exception.

but FSharp.Compiler exist:

This is because you have the Mono-released F# compiler in Mono 2.10

You have to adjust the explicit reference to this DLL in ./src/Services/FSharpCompiler.fs, replace the public key tokens on these lines:

./src/Services/FSharpCompiler.fs: static let asm = Assembly.Load("FSharp.Compiler, Version=2.0.0.0, Culture=neutral, PublicKeyToken=a19089b1c74d0809")

./src/Services/FSharpCompiler.fs: static let asm = Assembly.Load("FSharp.Compiler.Server.Shared, Version=2.0.0.0, Culture=neutral, PublicKeyToken=a19089b1c74d0809")

Am working on getting this fix added to the release

Look as fixed. Now when I try to open .fs files I get another exception:

System.TypeLoadException: Could not load type 'System.Collections.IStructuralEquatable' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

What about bug with System.Lazy when I try to do any doings with projects?

Looks like another issue with Mono 2.10. Can you use Mono 2.8?

[funnelweb]

btw what did you change those lines in ./src/Services/FSharpCompiler.fs to?

[o01eg]

I change PublicKeyToken=a19089b1c74d0809 into b03f5f7f11d50a3a

[funnelweb]

Very old issue, closing this out
