Could not load file or assembly “xxx.dll", PublicKeyToken=null” or one of its dependencies. The system cannot find the file specified in .NET 4.0

After we virtualized a production machine and booted this virtualized machine, .NET reported some errors after re-registering .NET 4.0 on IIS7 these error where resolved, but one WCF service kept on logging the error:

Could not load file or assembly ‘App_Web_squ1ikqu, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified.

Solution

The error was resolved after stopping all application pools in IIS7 and deleting the temporary internet files in the following folders:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files
