using System.Reflection.Emit;

public class Program
{
    static void Main()
    {
        AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(new
AssemblyName("Dummy"), AssemblyBuilderAccess.Run);
        ModuleBuilder modb = ab.DefineDynamicModule("Dummy");

        TypeBuilder tb1 = modb.DefineType("Interface", TypeAttributes.Interface
| TypeAttributes.Abstract);
        tb1.DefineTypeInitializer().GetILGenerator().Emit(OpCodes.Ret);
        tb1.DefineMethod("m", MethodAttributes.Public |
MethodAttributes.Virtual | MethodAttributes.Abstract);
        tb1.CreateType();

        TypeBuilder tb2 = modb.DefineType("Class", TypeAttributes.Sealed);
