2.0.0

This release updates to .net 7.
Due to the large breaking changes in Orleans 7.0.0, this release drops support for .net standard 2.0. If you need support for earlier versions of Orleans and .net, please use the 1.X releases (which will still receive bugfixes as needed).

Due to the new serlialization changes in orleans, it is now necessary to annotate your Hub messages with the GenerateSerializer annotation. See the readme or examples directory for examples.
