Could not load file or assembly 'App_Web_c4z8pqdo,

Question

User260983704 posted

 Hi, I'm on ASP.NET 2.0 and using Web Deployment Project to build assemblies by folder. I have been using these just fine and all of the sudden I've started receiving this error.

Could not load file or assembly 'App_Web_c4z8pqdo, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Exception type 'System.IO.FileNotFoundException' was caught.
Source: App_Web_zkh13vfe
Target Site: Void __BuildControlTree(ASP.artists_controls_artistheader_ascx)

The app has been working fine and there are not any errors on the page or control. App_Web_c4z8pqdo may have been the name of the assembly before WDP ran and merged the assemblies into folder specific names, but now the assembly is called Artists.Controls.dll. It shows FileNotFoundException, but the file is certainly there.

 As soon as I copy over the exact same assemblies (without even rebuilding) into the live bin folder, everything starts working again just fine.  Could the dll files be getting corrupt on that particular folder/file? Why doesn't it reference the name of the assembly as it is?
