Library with shader effects for use with WPF.

Build

The projects makes use of the Shader Effects BuildTask from WPF Futures. Since some of the effects require pixel shader 3.0 ShaderBuildTask.dll needs to be replaced with a modified version.

To do so install Shader Effects BuildTask and copy the provided version under \ShaderEffectLibrary\ to %WinDir%\assembly\GAC_32\ShaderBuildTask%Version% as administrator or use the gacutil. This allows you to compile .fx files under the ps_3_0 profile.

You might also need to install the DirectX End-User Runtimes
