Use System.Text.Json for JSON processing in ASP.NET Core
If you worked with earlier versions of ASP.NET MVC and ASP.NET Core, you are probably aware that these versions use Json.NET library for the sake of JSON processing.

The good part is, you can still use Json.NET if you so wish. So, you have two options now as far as JSON processing is concerned - either use in-built JSON API or use Json.NET. The in-built support for JSON serialization and deserialization comes from System.Text.Json namespace. In this article you will learn to use the System.Text.Json for serializing and deserializing JSON data during Web API communication.

But when you share your project code with others (say through a version control system) those details are also shared with others. Another example could be access keys or API keys. You might not want to share these details with others. Luckily, ASP.NET Core and Visual Studio provide an easy way to deal with this requirement through what is known as User Secrets.

Dealing with MongoDB DateTime in ASP.NET Core
