title: Is it possible to transform an IObservable<T> to an IAsyncEnumerable<T>
body: <p>I have an observable <code>IObservable&lt;T&gt;</code> / <code>ISubject&lt;T&gt;</code> and want to return that by using SignalR. SignalR has the concept of async streams where you have to return an <code>IAsyncEnumerable&lt;T&gt;</code>.</p>
  
  <p>How can I transform an <code>IObservable&lt;T&gt;</code> to an <code>IAsyncEnumerable&lt;T&gt;</code>?</p>
