Blazor WebAssembly Support

There are several issues when working with Blazor WebAssembly projects that need to be worked out.

Async Issues with GetAwaiter().GetResult()

HttpClientHandler UseDefaultCredentials Issue

We need to check the dotnet runtime issues for existing issues or report a new one as this is where the Blazor team handles these kinds of issues.
