In one of my previous articles, we discussed self-hosting web api using windows application. Continuing on the same paths, we will now discuss how we can self host the web api, using
OWIN custom host. So let’s start with it.
Add a new Console application and let’s call it
Next, in order to create a
webapi and use
OWIN custom host, we add references to
Microsoft.AspNet.WebApi.OwinSelfHost, using nuget package manager. This will not only add the references for the
webapi but also the
OWIN components, along with the other required dependencies.
Add a new
webapi controller class. We remove all the methods and add a simple
GET method to get sum of two random numbers.
Add a new class named
Startup.cs. This is as per the
OWIN specifications. Use the
HttpConfiguration class to create the
webapi routing template and add it to the request pipeline using the
appBuilder.UseWebApi method, where
appBuilder is of type
Program.cs file and start the server using the
WebApp.Start method, spcifying
StartUp class as the entry point for the settings required. This is the
OWIN specification of starting the server in the custom host.
Now simply run the application and the server is started.
To test the
webapi, we will use the Chrome browser Postman extension. So enter the url of the
webapi, which we specified in the
Program.cs and Send the request. See the results are received.
Easy to host, isn’t it. If you learnt it than do share it. Happy coding…!!!
