Temporary asp.net files

Visual studio, when it builds, runs, tends to create and use temporary asp.net files. Some compilation, and runetime errors, even when fixed are throwed/showed, because the cashed version of a logic is used, a code that does not exist any more in a project. Each time when I face this problem, I search a web, and it takes me some time to find this path:

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

Delete it all.
