I am getting the above error. I get good build but when i run web application, i get 'Could not load file or assembly 'businesslogic' or one of its dependencies. Access is denied.' 'Could not load file or assembly 'businesslogic' or one of its dependencies. Access is denied.' . I have given the Full Control permission to Temporary ASP.NET Files in Framework64 folder. Below are the details about the error. I checked the dll in separate project. It do not have any error. I got good build for the businessLogic project dll. So I don't understand what could be error.

Thanks, any suggestion??

I have given the Full Control permission to Temporary ASP.NET Files in Framework64 folder.

Yet your exception clearly states the path is not using the Framework64 folder:

LOG: Using machine configuration file from C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\config\\machine.config.

You might want to start there and re-check your permissions.
