In previous posts for ASP.NET Web API, we’ve discussed how to get and post data to our REST web service. The service will be hosted then directly in IIS. Today I would like to make a small demo of ASP.NET Web API for streaming video in a self-host application. The self-host will be implemented by using Owin/Katana. Having this feature you can enable a web service embedded in your application and streaming data to any app connecting to your PC app.
