I'm trying to work with artists to show them how to author in XAML with Noesis. It is embarrassing to have it repeatedly crash in Unity every time they make a change. This is within a vanilla Unity 3D project with the 3.1.7 plugin.

We made a small one line change in the quest sample and the crash above happened. Unity 2022.2.12f1.

Each crash dump seems to be a different issue.

The first one (from 3.1.7 version) happens during assembly reload.
The second one (from 3.2.0rc1 version) happens raising a PropertyChanged in a view model.
The last one (from a 3.1.8.12257 version I'm not aware of) seems similar to issue 0002512.

Let's investigate each one separately, the last one in the mentioned ticket.

Regarding the second one, it seems happened with our QuestLog sample, right? is there any steps to reproduce it?

The unknown version is likely the debug library provided here: https://www.noesisengine.com/bugs/view.php?id=2512#c8337

The 3.2 version was testing I did with a separate project -- but basically everything crashes for me whenever I edit a single line.

What is your Unity setting for: General -> Script Changes While Playing ?

We always work with "Recompile And Continue Playing".

Are you able to crash editing xaml/scripts in a separate project with just our plugin and samples?
From the crash you sent with Noesis 3.2, it looks like you were playing with the QuestLog sample, it happened just selecting a different quest from the list. Do you remember what you did to make it crash?

Consistently, the issue is always editing a line of XAML. It doesn't matter what the line is -- seriously. It doesn't matter.

We always work with "Recompile And Continue Playing".
OK, I always work with Recompile After Finished Playing. That setting is common to both Stellar Conquest and MBI. I have to do this because, like most projects in Unity, I do not support recompilation during playback.

See above video w/ crash dump. Clearly, this is an issue with Noesis on domain reload. Second, note that both of my projects use different app domain reload settings compared to what you are testing with. Lastly, the stack trace and location changes -- which again points to this not being a XAML change issue, but systemic with Noesis app domain reloads.

I upgraded from Noesis 3.1.8 to 3.2. Issue no longer manifests!
