Since upgrading to v1.61 I've been getting a lot of the following:

It always corrects itself if I rebuild the solution, but if I leave a form and come back to it later it frequently re-appears.

I was getting a lot of designer errors as well after installing 1.6.1. I don't know if it was just luck but in addition to cleaning each project in my solution and doing a full rebuild, I rebuilt all my partials, and re-set the SF Data Store connection and have had no further issues.

Thanks for the suggestion. I've tried that route but I'm still getting designer errors. I'ts only happending on two forms but so far I haven't been able to figure out what is unique about them. I did have an issue on one where I had dropped a tab control. When I later deleted it the tab definitions were left in the deisgner file which I manually cleaned up. When I get some time I'll try recreating the form and see if the issue persists.

That error shows up all over tons of forums throughout the Internet.  I found this KB article from Microsoft that says that there is a hotfix... I think it might be included in SP1 of VS, because I have a System.Design.dll with a newer version than this one.

The article says System.Design.dll v2.0.50727.193 should fix the problem, and the one I attached is the v2.0.50727.312 from my computer... I have VS2005 SP1 and VS2005 SP1 Vista Update installed.

Ben,

Thanks for posting the designer dll. I installed it but the problem remains. I was on VS SP 1 when the problem started. I'm not sure what Microsoft considers to be a "complex form" but it looks to me like it doesn't take much to reach that level.

Nope, we have several forms that always seem to do this...

On one of them, we can design it, and then if its designer is open when we run the project (debug), it immediately shows that message... but it comes back if we close the designer and re-open the file.  The others just quit working, so I dunno.

I've got a couple of forms that consistently show this message, but they always come back if I rebuild the application. I thought it might have something to do with Infragistics so I installed the latest hotfix for 2007 Vol 1, but that didn't help either. I guess it's just one of the features of VS
