Description Kolja Dummann 2013-02-24 15:03:33 UTC
I tried to compile this piece of code:

using System;
using System.Collections.Generic;

namespace test
{
	public interface IEntity<T>
	{
		T Id {get; set;}
	}
	public interface IRepository<TId>
	{
		IEnumerable<T> Get<T> () where T : IEntity<TId>;
	}

	public class Repository : test.IRepository<int>
	{
		public IEnumerable<T> Get<T> () where T : IEntity<int>
		{
			throw new NotImplementedException();
		}
	}
}

Which gave me an:

Compilation failed: 1 error(s), 0 warnings

/home/kolja/test/test/Main.cs(17,39): error CS0425: The constraints for type parameter `T' of method `test.Repository.Get<T>()' must match the constraints for type parameter `T' of interface method `test.IRepository<int>.Get<T>()'. Consider using an explicit interface implementation instead
/home/kolja/test/test/Main.cs(12,32): (Location of the symbol related to previous error)

kolja@UnimatrixZero:/build/net$ dmcs --version
Mono C# compiler version 2.10.8.0

Which compiles fine on Visual Studio.
