ConfiguredTaskAwaitable shall not be used

ConfiguredTaskAwaitable is a struct that is only meant for use by the compiler. It should be replaced by clean async/await pattern using async Task instead.

Hello @MrRickwi could you point me to the right documentation where I can learn about this a little more?

[MrRickwi]

If you look in Microsoft code reference, you will find the following comment:

/// <summary>Provides an awaitable object that allows for configured awaits on <see cref="System.Threading.Tasks.Task"/>.</summary> /// <remarks>This type is intended for compiler use only.</remarks> public struct ConfiguredTaskAwaitable {

This shows you that the struct should not be used.

Generally, use async Task<T> as result instead of ConfiguredTaskAwaitable<T>, and use ConfigureAwait(false) instead of ConfigureAwait(true), see here.

Most of the methods in MediaElement which return ConfiguredTaskAwaitable due to the ConfigureAwait should be rewritten like this:

public async Task<bool> ChangeMedia() { try { return await MediaCore.ChangeMedia().ConfigureAwait(false); } catch (Exception ex) { PostMediaFailedEvent(ex); } return false; }
