Pass a parameter to OWIN host

Question

I\'m self-hosting ASP.NET Web API and SignalR using OWIN. I start the server (on a console app) with this code:

using (WebApplication.Start(url))
         


        

Answer 1

The WebApplication.Start method has an overload that accepts a IServiceProvider as parameter, so it is possible to inject the data I want.

IServiceProvider serviceProvider = DefaultServices.Create(defaultServiceProvider =>
{
    defaultServiceProvider.AddInstance(myInstance);
});

using (WebApplication.Start(serviceProvider, url)){ ... }

Now, on my Startup class I only need to create a constructor that receives the IMyInterface:

public Startup(IMyInterface myInstance)
{
    ...
}
