Compile & Run

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

class C
{
    public static void Main ()
    {

        TypeBuilder tb;
        ILGenerator il_gen;

        AssemblyName assemblyName = new AssemblyName ();
        assemblyName.Name = "MonoTests.System.Reflection.Emit.ILGeneratorTest";

        AssemblyBuilder assembly = Thread.GetDomain ().DefineDynamicAssembly (
            assemblyName, AssemblyBuilderAccess.RunAndSave);

        ModuleBuilder module = assembly.DefineDynamicModule ("temp.dll");

        TypeBuilder tInterface = module.DefineType("I",
TypeAttributes.Interface | TypeAttributes.Abstract);

        MethodBuilder i_mb = tInterface.DefineMethod("M",
            MethodAttributes.Public | MethodAttributes.HideBySig |
            MethodAttributes.NewSlot | MethodAttributes.Virtual | 
            MethodAttributes.Abstract,
            null,
            Type.EmptyTypes);

        GenericTypeParameterBuilder[] i_typeParameters = 
            i_mb.DefineGenericParameters("T");

        tInterface.CreateType ();

        tb = module.DefineType ("T", TypeAttributes.Public);
        tb.AddInterfaceImplementation(tInterface);

        MethodBuilder mb = tb.DefineMethod("I.M",
            MethodAttributes.Public | MethodAttributes.HideBySig |
            MethodAttributes.NewSlot | MethodAttributes.Virtual | 
            MethodAttributes.Final,
            null,
            Type.EmptyTypes);

        GenericTypeParameterBuilder[] typeParameters = 
            mb.DefineGenericParameters("TT");

         tb.DefineMethodOverride(mb, i_mb);

        il_gen = mb.GetILGenerator ();
        il_gen.Emit (OpCodes.Ret);

        tb.CreateType ();

        assembly.Save("temp.dll");
    }
}


Produced temp.dll is invalid because of wrong Method Declaration Token

    MethodImpl #1 (00000001)
    -------------------------------------------------------
        Method Body Token : 0x06000003
        Method Declaration Token : 0x0a000002

NET verifier and runtime complains with

[MD]: Error: Class implements interface but not method (class:0x02000003;
interf
ace:0x02000002; method:0x06000001). [token:0x09000001]

Same error is not detected by Mono verifier
