I am doing User authentication in MVC using web API 2, OWIN.

Question

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

 

So, I uninstalled Microsoft.Owin.Security and its dependencies like Microsoft.Owin.Security.OAuth. And again installed 2.1.0 version for these both references.

Still its giing same error. TIA
