[Discussion] UseSignalR and UseConnections are marked obsolete

The methods UseConnections and UseSignalR, and the classes ConnectionsRouteBuilder and HubRouteBuilder are being marked obsolete in 3.0. And will be removed in the next major release after that.

The preferred method for using SignalR starting in 3.0 is to use Endpoint Routing. See example below.

Old code:

app.UseSignalR(routes =>
{
    routes.MapHub<SomeHub>("/path");
});

New code:

app.UseEndpoints(endpoints =>
{
    endpoints.MapHub<SomeHub>("/path");
});

This is the discussion issue for aspnet/Announcements#362.

What is you’re not using MVC, instead you’re using Web API… What’s the implementation for SignalR that is replacing the obsolete UseSignalR() method?

The code above is the same.

PS: MVC is the same thing as Web API in ASP.NET Core. It’s a single framework.

@VictorioBerra yes, there’s also MapController extension method for mvc
