Microsoft Store API : AppSubmissionUpdateSample.cs function calls works in Console App but not in UWP

Question

Documentation and samples are available here [ LINK ]

AppSubmissionUpdateSample.cs is a popular sample code from microsoft store api. In my experiment i found that sample code work fine in C# console app, but not in C# UWP App.

eg.

In C# Console APP
       // Get authorization token
                Console.WriteLine("Getting authorization token ");
                var accessToken = IngestionClient.GetClientCredentialAccessToken(
                    tokenEndpoint,
                    clientId,
                    clientSecret,
                    resourceOrScope).Result;

Above line works and fetches the results. but the same line of code, makes the application hang in C# UWP.

As a workaround i tried to rewrite the code in following way in C# UWP app, it then works, but i have no understanding why i am forced to use async/await, if anybody can explain to make me understand what's going on.

 In C# UWP App
     // Get authorization token
                Console.WriteLine("Getting authorization token ");
                var accessTokenX = IngestionClient.GetClientCredentialAccessToken(
                    tokenEndpoint,
                    clientId,
                    clientSecret,
                    resourceOrScope);
                var accessToken = await accessTokenX;    <----- forced to use async/await to work in UWP

Can anyone thow some light please. Thanks in advance.

Derive from document: Asynchronous programming

Each programming language supports the asynchronous pattern for the UWP in its own way:
