Answer 1

I came across this issue and I was confused because I have another application running the same code, only difference was I wanted to use await this time, and in the last application I used ConfigureAwait(false).GetAwaiter().GetResult();

So by removing await and adding ConfigureAwait(false).GetAwaiter().GetResult() at the end of the Async method I was able to resolve this.
