Use in Program.cs:
builder.Services.AddMicrosoftGraphClient();

Hi @ashelopukho, sorry, I might be missing something.
Is 'builder' a Microsoft.AspNetCore.Builder.WebApplicationBuilder instance?
So are you saying that Program has the same initialization of a Web Api 2 application?

@mmcossu, in this gist example - yes. But it's just for example.
