In my project I am using the OWIN library for user authentication. I have already installed the package, but when I run the project, the error is returned:
Could not load file or assembly 'Microsoft.Owin, Version = 2.1.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35' or one of its dependencies. The localized assembly manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
If someone can help, I appreciate it.
