 ## Call Graph APIs
-This example shows how to request an access token for a resource such as Microsoft Graph. When you use the Microsoft Graph service client in your code, you don't need to specify the resource explicitly, as the Microsoft Graph service client handles that automatically. In VB.Net, you'll need to add the `Microsoft.Graph` NuGet package and then add the `Imports Microsoft.Graph` at the top of the code file.
