I took some time over the past few days to write a short article on utilizing the D3D11 Shader Reflection API. When I originally got started with the API, I found it somewhat confusing to follow (which may have been due to my own shortcomings...) so I thought it could be helpful to provide some sample code and descriptions for everyone else to utilize. Its about 7 or 8 pages, so take a quick look. Here is the link:
I plan to update the article as more documentation become available, but this is certainly enough to get you started with D3D11 shader queries. If you take the time to read it, please let me know what you think about it. If you can think of some additional information that would be helpful, just let me know and I'll add it in (with a note specifying who was helping out too). Of course if you find some error or misinformation please let me know as well.
Good luck and enjoy D3D11 - this API is going to be around for a while [cool].
