The .NET DataStore project is available only in the PowerBuilder CloudPro and Professional editions.
You can use the .NET DataStore project to convert DataWindow objects to C# data objects and models and generate RESTFul Web APIs from the models.
A C# solution will be generated automatically to hold the C# models, services, and controllers. You can build and run the C# solution to expose the Retrieve and Update services as standard RESTFul Web APIs, so that they can be called from PowerScripts.
