Dear all ,hello ! I am a newbie and am learning .net for alteryx sdk. However, I can't get any help on DotNetCustomTools.pdf. That is, how to add a description for icon of custom plugin in the ToolBox. If you define a macro by .yxmc file, the description of macro is in the 'Description' field under the 'Meta info' tab in the Properties window for the workflow. When you click the mouse on the tool icon, the description will appear. Unfortunately, I can't find any code template to learn. maybe there is a line syntax like 'strDefaultDescription = "CustomDotNetTool is a useful tool.";' in SaveResultsToXml() or GetConfigurationGui() or other ? If this is a simple problem, can you help me? I need sample code to get it, Thanks again!
