Visual Studio taking long time to load solution

I know that this is a trivial problem but Visual Studio 2008 has suddenly started taking a开发者_StackOverflow中文版 really long time to load one particular solution that I have. While watching the status bar it appears to get stuck on one project. That project is, however, the most trivial of all projects and is a simple library with a few DTO classes in it.

Any ideas on how to solve this?

Have you added a Setup project to the solution? It seems to me that those take much longer to load than other types of projects.
