Using another thread in my application

Question

I have a Winforms application that hosts a WCF service.

Inside my Connect button click event, the connection is opening via BackgroundWorker in order to my UI responding while this connect s still in process (1 - 2 seconds) and after BackgroundWorker_RunWorkerCompleted event go to my other class and do my stuff.

Recently I added few Thread.Sleep while debugging and notice that it does not freeze my UI so after I search I found that is maybe because of the BackgroundWorker thread (am I right ?)

In my application I have the form class and another class that contain several events, the form class subscribe to those event and update my UI in this way:

        this.Invoke((MethodInvoker)delegate
        {
            // Update UI
        });

So my question is: is it OK to use another thread in this way and to use this.Invoke ?

Or do I need to do it in another way ?

Answer 1

Yes this is okay, its what background worker was invented for before the advent of async.

I recommend using async
