I've created a simple project to play with DirectX shaders. It's written in C# using SlimDX wrappers and runs as Windows Forms app. Pipeline is setup using DirectX 10 with HLSL shaders compiled from code. I was trying to test shader debugging and capture and all windows look fine. However when I run debug on vertex or pixel shaders it doesn't show the current variable and constant buffer values (I assume it should based on this walkthrough http://msdn.microsoft.com/en-us/library/vstudio/hh972447.aspx).
Can anyone suggest what might be causing this?
