Here in this post we will use C# .net code (for beginners like me) to see how to:

2. Get list of all Databases in a Cosmos DB
3. Iterate through all the Databases and get the list of all Collections (or Tables)
4. Get COUNT of all documents/items (or records) in these Collections
Click through to see how.
