MVC: Could not load file or assembly 'DotNetOpenAuth.Core,...'

description

Please remove the dependency on DotNetOpenAuth.Core from Microsoft.Web.WebPages.OAuth. Because I don't need to use DotNetOpenAuth on my project.

Could not load file or assembly 'DotNetOpenAuth.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246' or one of its dependencies. The system cannot find the file specified.

Stack Trace:

MVC doesn't have a dependency on OAuth. If you don't want it, remove references to both the WebPages OAuth DLL and the DotNetOpenAuth DLLs via NuGet.

I had this same problem, but realized that I need to clean the solution, delete the Bin directory for the application, and perform a full rebuild.

There were some old assemblies still hanging out in the Bin directory that were no longer referenced but were still being loaded.

@cdunlap, how do I do this? When I rebuild the project the bin directory gets recreated and repopulated. I believe this is happening because I once tried to build a deployable package. At the time I thought it was a sort of ad-lib option I could use or not use as I pleased, but something seems to have "stuck" in my build configuration. Is there any way I can undo it?
