A number of different C# templates are available for creating your application.
The template pack is available on NuGet.org at https://www.nuget.org/packages/IntelligentPlant.IndustrialAppStore.Templates
There are instructions on the NuGet page for how to install the templates package. Once installed, you can create a new project from the command line:
You can then add the project into a solution in Visual Studio and develop as normal, or you can use e.g. Visual Studio Code as your editor and compile using the dotnet command line tool. There are a couple of additional steps required after creating the project (detailed in the project readme file), but it allows you to create a running app in just a couple of minutes.
Let us know how you get on with it!
