34. Write pixel shader in HLSL Derive from the ShaderEffect class Expose whatever DPs you want accessible from your ShaderEffect Assign your DPs to Shader Constant Registers Compile your ShaderEffect using the Visual Studio build task – HLSL gets compiled at this time Apply your ShaderEffect via the new UIElement.Effect property
