In this unit, you learned what a driver is, how to connect MongoDB to a C# application by using the driver, and how to troubleshoot common connection errors.

When we build a C# application that connects to MongoDB, the application requires a set of libraries to interact with our MongoDB instance.

These libraries are referred to as drivers. MongoDB provides C# drivers for synchronous or asynchronous application code.

MongoDB drivers simplify connecting to and interacting with your database from an application.

Before we connected our application to our Atlas cluster, we first had to install the MongoDB driver by using the NuGet package manager.

After installing the driver, we used our connection string from Atlas to create a connection between our application and the database.

We used a single MongoClient instance because creating MongoClients is resource intensive.

Creating a new MongoClient for each database request will lead to performance degradation.

Finally, you learned how to troubleshoot common connection issues, such as: Network access errors and User authentication errors.

This knowledge gives you the foundation to troubleshoot the most common connection issues.

Now that you can successfully connect your database to your C# application by using a connection string, try implementing CRUD methods.

To do this, check out our units on CRUD, or take a look at the MongoDB documentation.

Congratulations on completing this unit. Until next time, keep coding!
