A simple .NET Windows Forms, build with VScode (unfortunately has no build-in UI editor). For demonstration purposes kept simple and easy to a minimum, using classic .NET 4.7. Project exists only of the initial Program.cs to start-up the Windows Form and the Form1.cs (no separate data layer, etc.).
The json file is received by a simple Http GET request and de-serialized into a simple <string, string>
datastructure, then added into a classic DataGridView.
Open the demo.sln with an .NET C# IDE, then build & run the project.
Alternatively can build and run the application by CLI, using dotnet run
.
