Hi Tom,

In SnapDevelop, if you create a ASP.Net Core Web API project, there will be an app.UseDataWindow() in StartUp.cs by default, it will parse all DataWindows when starting up.

If you create a xUnit project which is not ASP.Net Core Web API project, before initiating a DataStore object, please call the DataObjectFactory.LoadDataWindowLazy() method or the DataObjectFactory. LoadDataWindow() method to parse the DataWindows registered in .pbw files.

The DataObjectFactory.LoadDataWindowLazy() method only parses each DataWindow when used. And the DataObjectFactory.LoadDataWindow() method parses all DataWindows at one time.

If you still can't solve it, I suggest that you send the sample source code here.

Regards, Logan

Logan, 

The xUnit test project uses .net core as does the main web api project it is linked to.  In the startup class, we have this line of code:

            // Parse DWs
            DataObjectFactory.LoadDataWindow(null);
