Create a class for security metadata in ASP.NET Core 6 We’ll store API keys and API secrets in a .json file and read it in the application we’ll be building here.

In the “Create New ASP.Net Core Web Application” window, select .NET Core as the runtime and ASP.NET Core 2.2 (or later) from the drop-down list at the top. I’ll be using ASP.NET Core 3.0 here.
