Windows Phone 8 WCF Synchronous

Question

I have an app for WP8 and I would like to generate the reference to the services to call it synchronous instead of asynchronous. I need to make sure that one step is completed before start the second step.

Is there any way to do this ?

I've try to generate the methods sync instead of asynchronous but this option is not allowed in VS2013.

You can achieve, what you have mentioned, by using async/await keywords too, what you have to do is await the first method before calling the next method. That's it ( provided Step1 is properly implemented - you got your all the required stuff done for the next step to be taken ).

Suppose :-

Step1 method :-

public async Task Step1()
{
...
}

Step2 method :-

public async Task Step2()
{
...
}

Now you want to call the Step2 only after completing of Step1 .So, Just call them in order by awaiting the Step1 method(Task)

Public async Task/Void RunStep2AfterStep1()
{
  await Step1();
  // you will only get here only when you Step1() is completed successfully.
  await Step2();
} 

The below Async/Await helper Image give you proper flow of async/await.

Note :- Don't try to avoid the Async/Await they are much more powerful than you think, and if you think your requirement can't be fulfilled without them. Then, I think, you need to explore much.

Thanks :)
