Steps to reproduce the problem:

Compile the following C# code with mcs, referencing FSharp.Core.dll (shipped
with the Mono 2.10 packages)
using System;
using Microsoft.FSharp.Core;

// needs reference to FSharp.Core.Dll

namespace ConsoleApplication1 {
    class Program {
        static void Main(string[] args) {
            OptimizedClosures.FSharpFunc<int, int, int> t =
OptimizedClosures.FSharpFunc<int, int, int>.Adapt(null);
            // Error CS0029: Cannot implicitly convert type
`Microsoft.FSharp.Core.OptimizedClosures.FSharpFunc<T1,T2,TResult>' to
`Microsoft.FSharp.Core.OptimizedClosures.FSharpFunc<int,int,int>' (CS0029)

Actual Results:
  Compiler error (see code comment)

Expected Results:
