title: Frequent Access Denied to Temporary ASP.NET Files
body: <p>Literally every second time I run a big ugly web site project, I get an UnauthorizedAccessException, with a message pointing to a DLL, e.g. <code>Temporary ASP.NET Files\ctheweb\0d76d363\4695c81f\App_Web_vi6bbbpy.dll' is denied.</code>  I then stop and restart the project, and it runs fine.  I do some testing, debugging, fixing, run it again, and get the error again.</p>
  
  <p>I'm inclined to add a pre-build command to just clear that directory, but I always prefer to solve a problem with something other than a hammer, at least initially.</p>
