public static void End(IAsyncResult asyncResult)

Waits for the Task wrapped by the IAsyncResult returned by Begin to complete.

public static TResult End<TResult>(IAsyncResult asyncResult)

Waits for the Task<T> wrapped by the IAsyncResult returned by Begin to complete.

public static Task Unwrap(IAsyncResult asyncResult)

Extracts the underlying Task from an IAsyncResult created by Begin.

public static Task<TResult> Unwrap<TResult>(IAsyncResult asyncResult)

Extracts the underlying Task<T> from an IAsyncResult created by Begin.
