Simple example for MongoDB. Save and retrieve data from Azure Cosmos DB.
Create an Azure Cosmos Db as MongoDb
For creating a new MongoDb on Azure, search from the list of resources, Azure Cosmos Db. Then Add a new database and you see the following screen.
Overview
When you created a new MongoDb, you see an Overview where there are general information about how many queries the database did (split on insert, update, cancel, query, count, others).
Under Connection String you have the connection to use in your application. In this project you insert in Program.cs the connection string in the variable called connectionString.
DataExplorer
You can explorer all data in your Mongo database. Click on Data Explorer and you can see everything. Also, you can execute same queries.
You find an example application on my GitHub.
