ArcGis Pro version 2.8.3, SDK 2.9 for .Net

Hello All

    I'm having an issue with my Add-In for ArcGis Pro. I'm trying to override the Initialize method in the Module Class (Which my module is inherited from) and the Initialize method is not being called. I want to add some event handlers to warn users when they attempt to open a project using the Open command in ArcGis Pro Desktop. I want user to use my Add-In to open thier project. I want my module to initialize these events when ArcGis Pro opens. In my DAML, I set, autoLoad="true". But my overridden Initialize method is never being run (Confirmed when running in debug). Below is some of my code from the DAML and my module class:


<ArcGIS defaultAssembly="GraphicsFireDeskAddInPro.dll" defaultNamespace="GraphicsFireDeskAddInPro" xmlns="" xmlns:xsi="" xsi:schemaLocation=" file:///C:/Program%20Files/ArcGIS/Pro/bin/ArcGIS.Desktop.Framework.xsd">
<AddInInfo id="{1634e85e-8fa3-4db6-958c-b2e5f3ed133e}" version="1.0" desktopVersion="2.8.3">
<Description>GraphicsFireDeskAddInPro description</Description>

<insertModule id="GraphicsFireDeskAddInPro_Module" className="GFDC_Module" autoLoad="true" caption="Graphics Fire Desk Configuration" >
<!-- uncomment to have the control hosted on a separate tab-->
<tab id="GraphicsFireDeskAddInPro_Tab1" caption="Graphics Fire Desk" >

With 2.9 SDK running 2.9 desktop I

  1. added a new Addin Module,
  2. added an override for Initialize in Module1.cs
  3. Changed autoLoad=true in the Config.daml
  4. set a breakpoint in the Intialize() override
  5. Run Pro from VS in debug mode

When pro started it hit my break point.

If you do these steps (with a new module) and get different results, I suspect it might have something to do with running 2.9 SDK with 2.8 desktop. (I've always wondered how compatible this is).

I tested it too and it works.  Looking at your daml it seems to me that your namespace doesn't match what you're using in your code.



doesn't match the code's namespace: 

namespace Rfmss.GraphicsFireDeskAddInPro

Actually ... none of the OnPane overrides for Module are being called for me when I switch active panes - Init and OnUpdate are being called though.  Using 2.9.0
