What is the shortcut to clear “Temporary ASP.NET Files” folder before running application?

The problem is while running my code开发者_Python百科, i always come up to my old javascript files on VS.2010. I think its reason is Temporary ASP.NET Files folder.

How can i clear the temp folder when i press to F5?

You can run a pre/post-build action (if these are available) which will do the job.
