rebuild

I read some of the questions about precompiled headers but couldn't find a direct answer to that.

I usually rebuild my entire Visual Studio 2010 solution.

One of the projects in my solution is a C++/CLI project.

I thought that using precompiled headers in that project will increase the speed of the compilation.

After some experiments, it seems that using precompiled headers only slows the rebuild process.

Do precompiled headers only help with builds that didn't completely clean the old files?
