very long build - ASP.MVC 2 in VS2010

I'm developing Asp.MVc 2 application. In solution i've about 10 projects and i have no idea why bulid takes so much time - ~5 minutes.

I've tried to unload some projects, but it saves mayby 15 seconds.

I'd like to try and learn TDD, but writing and running tests will waste 80% time.

I'm using VS2010 and default MSBuild - is there any way to improve speed of building applications? 开发者_StackOverflow社区I don't know mayby other builder (NAnt could help?)

Have you tried separating your projects into logical solutions and not have them all in the same one? (I'm assuming you do). There is just some code that doesn't change so often that you have to build it all the time.
