Crashes since 2.9.0.9 about xmlnotepad

[lovettchris]

Oh, looks like a serious bug, I'm on it right away. So far I am not able to reproduce this bug using the files you provided in problems.zip and the double click steps you provided. Both files open fine for me so I end up with 2 xml notepad windows. But I see a similar issue posted here: https://answers.microsoft.com/en-us/windows/forum/all/microsoft-net-framework-encounters-jit-debugging/4aeaf8bc-304b-4c89-a372-ad470ccdc72e So I'm investigating, your trace above mentions NET48REL1, so I'll look for that version.

I see here that .NET 4.81 is available in a windows update for Windows 11 21H2, Windows 10 21H2 (LTSC), and Windows 10 22H2 according to https://devblogs.microsoft.com/dotnet/upcoming-availability-of-net-framework-4-8-1-on-windows-update-and-catalog/

I happen to be on Windows 11 23H2. What version of windows are you using? When I load my XmlNotepad into the debugger it shows the same versions of .NET have been loaded no problem (specifically version v4.0_4.0.0.0__b77a5c561934e089)

XmlNotepad.exe' (CLR v4.0.30319: XmlNotepad.exe): Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Xml\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.dll'. Symbol loading disabled by Include/Exclude setting.

I see the stack trace involves the "System.Windows.Forms.WebBrowser" and I see you are using "BrowserVersion" = "WebView2". Could you try changing your settings to use "WinformsWebBrowser" just to see if that makes a difference? If so we might have a webview2 installation problem.

The error message about [Single Thread Apartment] is confusing because the app already does that for the main thread, but this is a native callback so I'm now sure where that is coming from.

Can you run these too commands from a "cmd" prompt window and send me the output?

Can you also try uninstall 2.9.0.9 and re-install 2.9.0.8 and tell me if this works?

[lovettchris]

I found and fixed some issues, please also try this new version:
https://github.com/microsoft/XmlNotepad/releases/tag/2.9.0.10

[Pierre-de-la-Verre]

Hi Chris
thanks for your dedicated support. I tried now:

a) current Version 0.9 with WebView2:
I could open and close some files, but suddenly (maybe after closing my first "group of sessions) the problems began again

b) current version 0.9 with WinFormsBrowser:
no problems.

c) new installation of version 0.8:
no problems, neither with WebView2 nor with WinFormsBrowser

d) new installation of version 0.10:
no problems, neither with WebView2 nor with WinFormsBrowser

c) new installation of version 0.9:
see chapter a) above ..

It seems that you fixed the problem ;-))

[lovettchris]

Ok, phew! Glad it is fixed. Thanks for the thorough testing, and prompt reporting, you are really helping to increase the quality of XML Notepad :-)
