DirectX SDK Version Numbers and Download List
Working with different versions of various game engines on a regular basis, I never seem to have a copy of that particular version of the DirectX SDK required to compile the project.
Below is a list of DirectX SDKs and the corresponding values for D3DX_SDK_VERSION, D3DX10_SDK_VERSION and D3DX11_SDK_VERSION as defined in the d3dx9core.h, D3DX10core.h and D3DX11core.h header files, along with their download links to the Microsoft Download Center.
