#Assembly has a problem when loading unmanaged .NET DLLs - this affects the DirectX 9 code completion for example. #Assembly will be removed when we do the #D 2.0 port, thus you will have to live with missing code completion for unmanaged .NET DLLs for the 1.x branch. The .NET Reflection API in .NET 2.0 in contrast has everything I can dream of, which is why there will be no further work on #Assembly.
