Welcome to this MongoDB and ASP.Net Core Web API sample project. The aim of this project is to give you a working example of how you can use the power of MongoDB Atlas and .NET to create modern applications. This project is intended to be a companion project to the article How to use MongoDB Atlas with .NET/.NET Core from the MongoDB website.

The below diagram shows the overall architecture of the application and the following sections will explain the code more.

The GamesController.cs class is where the routes/endpoints for the api are defined. Each endpoint calls to a method in the GamesService.cs class.

The GamesService.cs class contains the code that uses the MongoDB.Driver NuGet package to carry out CRUD operations against your Cluster.

The Game.cs class acts as a model you can use throughout the project and the properties in it, map to the fields in the MongoDB document.

GamesDatabaseSettings.cs contains an interface and implementation that maps to the GamesDatabaseSettings section in appsettings.json and appsettings.Development.json. In this application, the connection string to your cluster is stored here, but normally in production, you would combine this with user secrets.

At the root of the project is the usual files that come out of the box with an ASP.NET Core Web API project.

The only file with changes made here is the Startup.cs class. Inside the ConfigureServices method, the appsettings code is pulled in and the Database settings and Games Service are added to dependency injection for use in other classes.

If your IDE supports it, you can go ahead and run the application from inside the IDE. If you prefer to run it from your terminal/command-line, you can use dotnet run.
