Here's a harder one, save an image from a render target using Windows 7 interfaces. (MSDN only shows the windows 8+ interfaces)
Yes, but CreateWicBitmapRenderTarget works since Vista SP2. It's look like a compiler error (bug?).

also thanks for all the hard work on this Trick. I won't be releasing a typelib for a long time. If I do it will most likely be a large all in one typelib, including all of DirectX, sort of like SharpDX/SlimDX for VB6.
Okay, then maybe i'll post that sources on CodeBank (after i add comments, fix bugs, and make more examples).

BTW, i accept the suggestions for the new demos.
