RowBuffer Class
Represents a row buffer that can be used with Table.CreateRow
Syntax
public sealed class RowBuffer : ArcGIS.Core.CoreObjectsBase, System.IDisposable  
Remarks
A row buffer is an in memory representation of the row that can be used to set field values before creating the row in the table. .
Example
Creating a Row
public async Task CreatingARow()

            //declare the callback here. We are not executing it .yet.
