We would like to host our GRPC service on IIS using HTTP2 with Windows Server 2019. There seems to be conflicting/outdated information online, so I was hoping someone with more experience could provide me with an up-to-date answer:

1). Does Windows Server 2019 IIS support GRPC & HTTP2?
2). Does Windows Server 2022 IIS support GRPC & HTTP2?
3). Can a .Net Framework 4.7 app successfully make async unary grpc calls to an IIS hosted service over HTTP2? (using WinHttpHandler). 2019/2022?

I appreciate any feedback.
