什么是欧文？ 它与Asp.Net有什么关系？

Question

Can anyone give me a brief description of owin?

What is its relationship between asp.net mvc external log in?

and relation to Microsoft.Owin.Security.Google?

Answer 1

You can read about OWIN at http://owin.org . That should give you some understanding about the structure and interface of the framework and how it is used to separate any midware, eg MVC from a concrete server process eg IIS. Microsoft wants to adopt this framework/interface to make middleware like MVC available on more systems. Currently (MVC5) MVC is not yet a OWIN middleware, but parts like authentication already are. So this is why you have some assembly like Microsoft.Owin.Security.Google referenced in your project.
