### What did you do?
Followed the instructions

### What did you expect to see?
The api compiling

### What did you see instead?
Error: The type or namespace name 'Api' does not exist in the namespace 'Google' (are you missing an assembly reference?)

### Anything else we should know about your project / environment?


Start by reproducing the tutorial on macOS Arm64 with .NET SDK 7.0.307 and review the tutorial project and its instructions. Investigate why the Google.Api namespace is unavailable, then confirm the API project compiles when the documented setup is followed.
