Limit the number of error popups

[nullchilly]

Problem Description

Every time there's an error (i.e. decompile error or OOM), DnSpy will nonstop spawn error popups making the computer unusable until DnSpy crashes

There are so many DnSpy popups that it formed a shadow effect

Proposal

Don't send error popups with the same message

Alternatives

No response

Hi, these errors do not appear to originate from dnSpy code itself but rather from the WPF framework. The decompiler in dnSpy is run on a separate thread with an exception handler configured so any exception raised there would not cause these popups. This can be seen when you observe decompiler errors causing green comment text in the output.

If the popups you are seeing can be isolated to a single file which causes the issue then it might be some trickery going on in that file to mess with the WPF renderer or something like that. If so, could you please send the file to me via email at [email protected]

If these popups occur for many different files with nothing in common then it is most likely something in WPF causing the large amounts of errors.

I have never seen such an error spam before.
