WPF .NET 7 - Remove the namespace from the build in ballon

[Zeleksonob]

Is there a way to remove the namespace name each time I'm shown a build in ballon?

[Lakritzator]

This is for the build in notification ballons, and that text is the title of the application process (or the name of the .exe) which showed it, to my knowledge you cannot simply change it.
That is where a custom balloon helps.

Thanks for the answer,
follow up question:
can I control the timeout of this ballon or is this apply also only to custom ballon?
If not, could you guide me or give me a hint as to where I can't find these windows templates for the ballon?

[Lakritzator]

If I recall correctly the timeout of the default balloon could be specified by the app when it's running under Windows 2000 or XP, after that (Windows 7 and later) it was controlled on a system level.

A yes, here it's documented: https://learn.microsoft.com/en-us/windows/win32/api/shellapi/ns-shellapi-notifyicondataa

About the custom balloon, if you look at the method ShowCustomBalloon (in TaskbarIcon) you can specify the timeout there.
