Chetan,
It sounds like you're working in VisualmStudio or using MsBuild. I don't know
anything really about either one with respect to WiX.
That said, setting an environment variable from a program has usually only
lasted until that program exits. I don't know where or when that C# code is
running but that could be a problem.
Also, running Candle as a prebuild command seems very wrong.
I looked very briefly at the VS integration and decided it wasn't worth my
time. Also, there are folks in my organization who do packaging but not any
development, so as the WiX trailblazer around here, I didn't want to depend on
stuff they don't have.
