How to Bind to a Task Result

Content in preparation.

Example 2: Binding to a task​

If you need to do some heavy work to load the content of a property you can bind to the result of an async Task<TResult>

Consider you have the following view model which generates some text in a long running process:

public Task<string> MyAsyncText => GetTextAsync();

private async Task<string> GetTextAsync()
{
  await Task.Delay(1000); // The delay is just for demonstration purpose
  return "Hello from async operation";
}

You can bind to the result in the following way:

<TextBlock Text="{Binding MyAsyncText^, FallbackValue='Wait a second'}" />

Note: You can use FallbackValue to display some loading indicator.
