如何使用Burn捆绑WiX安装程序？我可以在一个项目中制作它们吗？

I've been stuck for a while with WiX/Burn lately. My intention is to create an installer that unpacks files and downloads .Net Framework if it is missing. As far as I'm concerned, I should use some kind of bundle tool, Burn, for the .Net part and "normal" WiX to unpack the files. I have written the unpacking part (using SharpDevelop) and now I'm ready to make a bundler for that. How should I merge the Burn and WiX stuff? Do I have to create two separate projects, one for the MSI and one for the bundle?I've been stuck for a while with WiX/Burn latel
