Error connecting to undo manager of source file "whatever designer"

Posted 2007-06-14 03:50 PM in ASP.NET | Bugs.

This error is more than a little irritating, especially considering this is Visual Studio 2005 SP1. I'm getting this, now, for one file, every time I run my application.

The way I "fixed" it was to exclude the file from the Web Application Project, recompile, then re-include, the recompiles.

Seems to me that the error handler that threw this message box should spend more time fixing the problem automatically and less time informing me of a problem I can do little about. Maybe that's just me.

I get that too, amazingly annoying.

A few times I started a compile and came back and noticed that it stopped because of this stupid message which doesn't seem to affect anything.

I hope the person who have written this piece of code reads your blog... and he's already fixing it! I got it too, and it's irritating!

A simpler two-step fix is to:

1) Right-click the designer file and select delete
2) Right-click the aspx file and select Convert to Web Application

I get this frequently too, and I think it stems from some sequence of editing the aspx file while the app is running in debug.
