Matthew Henderson does a demo for Scott Hanselman to show how simple it can be to build serverless apps that leverage bindings for Microsoft Graph (e.g., reading data from a Microsoft Excel spreadsheet in a OneDrive folder) to avoid writing laborious initialization and authentication code, all using Azure Functions.
