In order for the Rocket Enterprise extension to work with .NET COBOL projects, you need the following software installed:
Your .cblproj or .sln .NET COBOL projects and solutions must be created with Enterprise Developer for Visual Studio. The .cblproj file must be stored in the same folder as the .sln file, or in a subfolder of it.
You can use a command provided by the C# extension to generate the tasks.json and launch.json file for your project.
This generates a tasks.json and a launch.json file in a .vscode subfolder within the folder that holds your sources. You can use these files to build and to debug your project, respectively.
Alternatively, if you do not want to create a tasks.json file,Rocket Enterprise provides an auto-generated build task for each .NET COBOL project file in the open folder:
