Clean conflicting class files from Temporary ASP.NET Files

Question

Class file Conflicts in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\ is preventing me from building the solution. Even though I try emptying out the folder, each time Visual Studio starts the build process, it brings in the class file in to the temp folder with the same folder name. If I restart the machine or leave it overnight, project build without error. Is there anyway to tell Visual studio to delete/ignore/clean any lingering class files that could be in the temp folder?

Clean solution option in VS doesn't work either. Class file in conflict are from the App_Code folder.

Answer 1

Adding this as an answer here directly: move the temp location for easier cleaning or a pre-build event

<system.web>

   <compilation tempDirectory="d:\TempASP.NETFiles\">

      ...

   </compilation>

</system.web>
