I'm trying to create a dynamic proxy. I have define a typebuilder :

AppDomain myDomain = Thread.GetDomain();
AssemblyName assemblyName = new AssemblyName();
assemblyName.Name = "Intercep";

asmBuilder = myDomain.DefineDynamicAssembly(
assemblyName,AssemblyBuilderAccess.RunAndSave);

modBuilder = asmBuilder.DefineDynamicModule(asmBuilder.GetName( ).Name, false);

typeBuilder = modBuilder.DefineType (asmBuilder.GetName().Name + ".__Proxy" + interfaceType.Name + targetType.Name, TypeAttributes.Class | TypeAttributes.Public,
targetType.BaseType, new Type [] {interfaceType, typeof EmitedInfo)});


fbTarget = typeBuilder.DefineField ("target", typeof(object), FieldAttributes.Private);

fbIface = typeBuilder.DefineField ("iface", typeof (Type), FieldAttributes.Private);

Type[] types =new Type [2];
types[0] = typeof(object);
types[1] = typeof(Type);

ConstructorBuilder Ctor = typeBuilder.DefineConstructor(MethodAttributes.Pub lic,CallingConventions.Standard, types);

And then when i try this

type= typeBuilder.CreateType();

an invalid operation exception

I would appreciate any kind of help, thank you very much.
