0.8.0 upgrade guidelines?

[Atulin]

I'm seeing an [Obsolete] warning on my current code:

var fileName = $"{folder}/{name}.{ext}"
var result = await b2Client.Files.Upload(bytes, fileName);
                                  ^^^^^^ obsolete

It seems this method was deprecated in favour of one that uses uploadUrl parameter, and that one was obsoleted in favout of one that uses B2FileUploadContext.

Problem is, nowhere in the documentation is there any mention of B2FileUploadContext, at all. The class has a metric ton of non-nullable properties too.
