I created a special module for excluded exceptions, which allowed me to get more information about the origin of the error and possible resolution of the problem.

Here is a link to a codeplex project that has code for the exception module: http://unhandledexception.codeplex.com/SourceControl/changeset/view/80132

I look at the text "Unable to find assembly" Company.Common, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null '. "

Are you missing a build or a problem with the version?

The error says that the assembly was not found. If it is located in the bin folder and formatted correctly, is it possible a permission error?

Does your Company.Common assembly have permissions to read its IIS AppPool identifier?

You can also do a double check to make sure the assembly is listed in the system.web / compilation / assembly section of your web.config.
