New Post: custom ui

The simplest way to proceed is to call Compiler.BuildMsiCmd instead of Compiler.BuildMsi. This way you will be able to inspect both WiX file and the batch file invoking the candle and light.

This can help you to figure out where and how you custom wxs should be incorporated. Most likely the cmd file should have some extra params.

If you manage to solve the problem please share your solution and I will add it to the samples library and/or reflect it in the WixSharp compiler.
