Creating Azure Function with Visual Studio doesn't work

Question

Installed VS with the options (and a few more) named here: https://learn.microsoft.com/en-us/learn/modules/develop-test-deploy-azure-functions-with-visual-studio/2-develop-and-test-azure-functions-locally

tried the exercise here: https://learn.microsoft.com/en-us/learn/modules/develop-test-deploy-azure-functions-with-visual-studio/3-exercise-develop-and-test-azure-functions-locally

Everything went well until 'Create the WatchInfo Azure Function' (see picture on the site).
I don't have 'New Azure Function' under 'Add'.

Furthermore I have these errors: Unable to find packages
I'm missing something but what?

This is installed now, what do I have to add?

Answer 1

ah, found out how to update / install missing Nuget Packages.
Package Source was missing (https://api.nuget.org/v3/index.json).
