Hi all,
I am following this link and created a very simple sample. The X++ code as well as the .NET code is given below. I did a compile, compile forward and Incremental CIL on AX after creating the X++ side of code.
I quite do not understand why this error is coming. The error is :
Error:
Message: Cannot create an abstract class.

analytics.ReturnFlatDataSet = true;
var datasetResult = client.ExecuteDynamicQuery("DemoQueryBuilder", args, ref paging);

I have the same question (0)
Hi,
Figured it out, I was using:
MyQueryServiceRef.Paging paging = new MyQueryServiceRef.Paging();
Should have used :
MyQueryServiceRef.Paging paging = null;
