Implement Self-Host project practice based on ASP. NET WebAPI OWIN, webapiself-host
Reference

Host ASP. NET Web APIs do not necessarily require IIS support. We can use any type of applications (console, Windows Forms Application, WPF application, or even Windows Service) as the Host using Self Host.

I. Summary

4.1,Last Review

In the previous issue, we shared the implementation of client-to-server communication projects based on open-source SuperSocket. In practice, the WEB page was submitted and printed to the WEB server, the WEB server pushes the received printed data to the specified client through the Socket communication server.
Can we simplify the above call procedure?
Directly let the Client Print the data to the local client, without the need to use the Socket communication server for transit.

4.3,The problems we want to solve today can be summarized as follows:

How does one allow the WEB Client to directly access the local Desktop client through HTTP, just like accessing Web applications on Remote IIS?

4.4,Implement the Self-Host solution for WEB Applications

Implement simple Http Services (. NET 2.0 +) through HttpListener)
Self-host SelfHosting Based on WCF Stack
Use ASP. NET HttpSelfHost to host WebAPI services (. NET 4.0 +)
Use ASP. net owin to host WebAPI services (. NET4.5 recommended by Microsoft)
And so on ......
