Description Andrey Akinshin 2014-08-13 00:27:32 UTC
*** Overview ***
.NET Runtime should throw TypeLoadException when TypeBuilder.CreateType() creates Type with a declared private interface. Mono does not.

*** Steps to Reproduce ***
The minimal example:

using System;
using System.Reflection;
using System.Reflection.Emit;
using System.Threading;

namespace FooProject
    class Program
        static void Main()
            var assemblyBuilder = Thread.GetDomain().DefineDynamicAssembly(
                new AssemblyName("FooAssembly"), AssemblyBuilderAccess.Run);
            var moduleBuilder = assemblyBuilder.DefineDynamicModule("FooAssembly");
            TypeBuilder typeBuilder = moduleBuilder.DefineType("Foo", TypeAttributes.Public,
                typeof(object), new[] { typeof(IFoo) });

        private interface IFoo

*** Expected Results  ***
Microsoft .NET Runtime throw TypeLoadException for the line typeBuilder.CreateType(); because of the IFoo interface declared as a private. 

*** Actual Results ***
Mono run this code without any Exceptions. 

*** Platforms ***
I check it on:
Kubuntu 14.04, x64, Mono 3.2.8 (Debian 3.2.8+dfsg-4ubuntu1)
Windows 8.1, x64, Mono 3.3.0 (master/6cd4ddc)
Online compiler http://www.compileonline.com/, Mono
