I have a fresh MVC5 project made from Visual Studio 2013, which works fine when I try to launch it locally. However, when I publish to my Azure website, I get this front page:

Could not load file or assembly 'Microsoft.Owin.Security.Cookies' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

And the stack trace:

[FileLoadException: Could not load file or assembly 'Microsoft.Owin.Security.Cookies' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)]

I have version 3.0.0 of Microsoft.Owin installed, and it says the same thing in my Web.config and packages.config. How can I fix this?

Try to :

  1. Upgrading Microsoft.Owin.Security from 2.1.0 to 3.0.0
  2. Upgrading Microsoft.Owin.Security.Cookies from 2.1.0 to 3.0.0
  3. Upgrading Microsoft.Owin.Security.OAuth from 2.1.0 to 3.0.0

After I have upgraded above packages, the problem is resolved.
