Using Azure Cosmos DB with C#
In this lab, you will gain experience using C# and Visual Studio to connect to and use Cosmos DB. You will RDP into a Windows VM set up with Visual Studio and update a pre-built solution with the appropriate Cosmos DB C# code to connect to Cosmos DB, upload documents, and use the SQL API to query documents. When this is complete, you will run a console application to see everything working and can go back to the Azure portal to verify the documents were saved. Upon completion of the lab, you will have gained the experience required to work with Cosmos DB using C#.
