TrySetResultAsync missing in 120 version, how to handle this?

[lofti198]

Windows 10, .NET framework 4.8, updated from 91 to 120 version and getting this error:

Error CS1061 'TaskCompletionSource' does not contain a definition for 'TrySetResultAsync' and no accessible extension method 'TrySetResultAsync' accepting a first argument of type 'TaskCompletionSource' could be found (are you missing a using directive or an assembly reference?)

What is the best way to handle this?

The extension method got removed with the upgrade to .NET Framework 4.6.2 here:

You can create a TaskCompletionSource with TaskCreationOptions.RunContinuationsAsynchronously option and just use TrySetResult.

var tcs = new TaskCompletionSource<bool>(TaskCreationOptions.RunContinuationsAsynchronously);

tcs.TrySetResult(true);

Works awesom!
