Add-In version conflict

sonj — Tue, 11 Mar 2025 11:47:34 GMT

We upgraded the tool from 2.9 to 3.4 and working fine in the development system but failed while loading in the test system. The error says "The add-in cannot be loaded because it targets and incompatible version of ArcGIS Pro. Current verion 3.4 add-in targets:2.9"

See the attachment for a better understand.

Did you follow all the steps on the migration page from the documentation?

three possibilities:

1. Did you update your config.daml to target version 3.0 and higher?

2. In your .csproj file for your solution ensure the following tags are updated to:

<TargetFramework>net8.0-windows</TargetFramework>
<RuntimeIdentifier>win-x64</RuntimeIdentifier>

3. ArcGIS Pro requires .Net Desktop Runtime 8.0.x, this must be on both your build and deploy machines. Also, all .Net references in you Visual Studio project need to be updated to use 8.0.x -or .Net 4.8 for any WinForms.

and

4. run the upgrade tool as referenced by KenBuja

win10-x64 is not supported with Visual Studio 2022 and .Net 8.0.12, use win-x64 instead.

Thanks @RichardDaniels, it worked after changing to win-x64.
