Fix for Unhandled WebException in Async call

[Brianster]

Hello I came across a post in the form the MusicBee was having an issue with this an unhandled WebException with the callstack below and it has been fixed in MusicBee.

I have a similar issue in an unrelated project when calling System.Net.Http.HttpClient.GetAsync and was wondering if the MusicBee developers were able to find the root cause and could share the fix?

Thanks

Brian
