Along the course of this chapter, we went through the foundations and basics of NoSQL databases, starting with their historical evolution and the several types of architectures and peculiarities linked to this storage approach and a list of the most typical implementations we can find today.

We also explored the correct manner in which the CRUD operations should be managed in these contexts from a general-purpose point of view.

Then, we moved on to MongoDB, analyzing the details of its installation and management in a Windows system, prior to starting the use of a MongoDB instance by means of its default (command-line) tools in order to operate and import, manipulate, list, and modify its contents without any external tool in order to study the low-level mechanisms behind its usage.

Finally, we used the C# driver available on the official MongoDB website in order to accomplish the same CRUD operations from a Console application, including the most typical actions required in LOB applications.

In the next chapter, we'll look at how to use some of the—many—resources and projects available as Open Source, which are monitored and actively supported by Microsoft these days, and that includes the Roselyn services, the new TypeScript language, and others.
