Below is the process for adding a Graph Console App -

Answer 1

this fixed it for me:

dotnet nuget add source --name nuget.org https://api.nuget.org/v3/index.json

apparently it's a missing step from the Exercise to add a nuget source or assumes the user has Visual Studio installed (not sure if that would do it either); it is not indicated in the prerequisites for the Exercise:

.NET SDK - v5.* (or higher)
Visual Studio Code

I have both installed and it still failed until I ran the command above to set the nuget source.
