Does it make any difference if you delete the bin and obj directories under C:\Users\erichray\source\repos\FunctionApp2\FunctionApp2\ and try to build again?

Those seems to be warnings, but reported as errors. Can you check your project build settings and see you have enabled "all" warnings as errors? https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-options/errors-warnings

[erichkray]

Deleting bin and obj does not resolve the issue. The default setting for VS does seem to include $(WarningsAsErrors);NU1605, but removing this or even setting Warning Level to 0 - Disable all warnings does not seem to help.

This is all just the boilerplate project generated by the "New > Project" menu.

Are you still experiencing this issue? If so, Could you share a link to a minimal repro? I could not repro this on my side.

I was able to unblock myself. IIRC, I had to manually install .NET 6 SDK to get it to successfully run.

Great! Closing. Please open a new issue if you run into other issues.
