@LarsJ and others.
Is it good time to start separate GitHub project for this our project to have cohesive UDFs ?

Do you assume that "Shell.Explorer.2" will not work on Win11, or did you try it? I'm still on Win10, but search results indicate it still should work,

Try it:

It works but result is not good because based on IE engine.

Hi @mLipok

just a clarification, when you consult the WebView2 documentation on the Microsoft website, to remain compatible with the environment created here by @LarsJ you need to choose the pages relating to Win32/c++ and not those relating to .NET or c#
Make sure you choose the page versions as highlighted by the red circle in the images below:

https://learn.microsoft.com/en-us/microsoft-edge/webview2/webview2-api-reference?tabs=win32cpp

https://learn.microsoft.com/en-us/microsoft-edge/webview2/reference/win32/?view=webview2-1.0.1938.49

Too bad all of that is locked behind Microsoft's downstream Edge browser filled with trackers 🤬.

This is why we need copyleft licenses like GPL, so that companies can't just leech off of good open-source work, make a few improvements and sell that off as their own product

Also the JSON viewer is a joke, Firefox has had a much better viewer since forever and you don't even need to enable it with a flag

@mLipok I would love to see such GitHub project. I would start contributing (but first learning about the API structure of WebView2 etc.).
Is there any mature approach already live anywhere here? I guess only what is listed/posted here, right?

Btw: I did not read all about WebView2 here in this thread, but I probably will. Let's see what @LarsJ already achieved 😇 .

Best regards

[mLipok]

@LarsJ what is your opinion about moving to GitHib ?
