In my first article, I have described Azure Cosmos DB Table API, and as I have promised you in this article, I will explain the Azure Cosmos DB SQL API, but I would do it differently. To make the article more comprehensive, I have included two other topics, Entity Framework Core and Blazor. Entity Framework Core uses Azure Cosmos DB SQL API.

The Demo application is used CosmosDb Emulator as a backend and Entity Framework Core as ORM with Cosmos DB Provider, and the rest is done with Blazor.
