AzureResourceDiff

This project gives the basis code for an Azure Function (AzureResourceFunctions) to take daily snapshots of the Azure registered resource providers for a subscription, calculate a difference to the preceding day, and save the results in a database. Then the frontend web app (AzureResourceWeb) contains a web page that loads the information, and shows the last 20 days of changes.
