Let’s consider this code:

public async Task TheBestMethodEver1()
{
// code skipped
await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
  // code skipped
});

}

public Task TheBestMethodEver2()
{
  // code skipped
  return Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
  {
    // code skipped
  }).AsTask();
}

Any of these methods can be called like:

await TheBestMethodEverX();

What is the difference between these two methods and why should I use the first one usually?

    The first one has a compiler-generated state machine and creates additional garbage on the heap. Therefore the second one is preferred.
