Triggering an async operation in from mvc controller

Here is my scenario.

I want to create a web endpoint that will kick off a service that may be long-running, perhaps 20-30 minutes. I'd like to return an HttpResponseResult immediately and trigger the service to run asynchronously, instead of having to wait for the service to complete before returning a response to client.

What is the easiest way to go about doing this? I don't need to return any sort of result from the service, just trigger it.

Just run a task using Task.Run(() => <trigger service call> ) and ignore the return value. The only down side of this is that it will consume a thread from the thread pool. If the service has an asynchronous version of the operation you are calling you can use a TaskCompletionSource

SignalR will be my choice to do this kind of behavior. Tutorial is here.

Basically, a client invokes a server method/action and is 'done' (you can continue and do whatever y you want in the client side). Once the server is done it pushes data/notification to client via RPC.

On the server side you can execute the code anyway you like, synchronously or async.
