StackTrace does not show up on stack trace when use AddInManager 2025

[jmosh6]

Describe the bug
I have noticed that the line # does not appear in the stacktrace of the exception. This seems to only be the case when loading my application through AddInManager rather than fully loading it in. I can see that I do have a .pbd file in the folder where the .dll exists, so I don't think it is that. My debug type is as follows. Full

This is a screenshot of a TaskDialog displaying the stacktrace when the application is fully loaded in.

This is a simple project I created to demonstrate the issue. The issue can be reproduced by

First Scenario

• installing this project,
• clicking "Do Not Load

• Run "TestCommand"
• Trace line should not be shown.

Second Scenario

• Re-opening Revit
• clicking "Load Once"
• Run "TestCommand"
• Trace line should be shown.

Hi @jmosh6 , this is result showed from my side use add-in manager by using your project example, I haven't change any thing, can you try with version of revit 2022 or lower version 2025, this is test in revit 2022

Hi @chuongmep, thanks for the quick reply.

I failed to mention, that it is isolated to Revit 2025. I did just test it on Revit 2022 as a double check and it worked perfectly fine.

Hi @jmosh6 , I haven't have a chance to explore with revit 2025 yet, just basiclly Revit 2025 run in .net8 , so I guess have something need to recheck and verify

Hi @chuongmep,
I just wanted to check in regarding this issue.
It seems that the same problem occurs in Revit 2026 as well.
Do you have any plans or timeline for when this might be resolved?

Thanks again for your work on AddInManager — it’s been very helpful!
