Incremental builds in VS2010

How can i turn on incremental builds in VS2010? I've noticed that my project rebuild everything each ti开发者_如何转开发me i press build. Is there any option in VS to turn this on? Or should i modify *.csproj on my own?

Projects should build incrementally already (just make sure that you do Build instead of Rebuild). The best way to check if incremental building works is to run the build from the command line. The second time you build it should take almost no time.

If things are still getting rebuilt, then perhaps you've modified your projects in some way that's messing up with the build order. Looking at the build logs (via the /v option) can help you poinpoint what's going on.
