Call web APIs from Blazor topic

[guardrex]

From @danroth27 at Add topic on calling web APIs from Blazor ...

• HttpClient
• JSON helpers
• Setting fetch arguments for the request (see Implement Request credentials  blazor#399 (comment))
• Making cross origin request

From @stimms ...

This sounds interesting. Do we want to surface the fact that the HttpClient is not the actual HttpClient and is actually fetch or is the feeling that the abstraction is so good nobody needs to know?

Nevermind ..... I just answered my own question. I was actually looking at the use of HttpRequestMessage and mistakenly thought that WebAssemblyHttpMessageHandler came from that. It actually comes from HttpMessageHandler.

[UPDATE] Look'in good! I should have this new topic in this afternoon (Monday, 5/20).
