Hi

I have many user controls in my web application project. I have added a label in one of the user control, but its designer.cs file is not getting updated. Also I tried with removing the designer.cs and regenerating using "Convert to Web application", but I am getting this error "Generation of the designer file for failed: Collection was modified; enumeration operation may not execute."

What do you mean by "designer.cs"? There are no well-known fixed-name files. Do you mean just a part of file name?
Then I'm sure you are mistaken.

it is about page.designer.cs(e.g. default1.aspx.designer.cs) or usercontrol.designer.cs(e.g. uc1.ascx.designer.cs) . Hope it is clear my question now.

Thank you for confirmation. As I say, I don't believe your observations are correct. However, if you think they are, you would need to provide step-by-step instructions to reproduce the problem. 1) Run Visual Studio, 2) In Solution Explorer, select project type... and so on.

You would need to generate most simplified code text for this exercise. But chances are, if you try to pay so much attention for detail, the problem may disappear... :-)

yes, in the case of code written by us, but if it is written by someone and need enhancement in it for that we can not rewrite everything :). still I'm trying. For the another error "Generation of the designer file for failed: Collection was modified; enumeration operation may not execute." I got the solution that Microsoft has released RC3 for that. I will check with that.

In other words, you don't know how to reproduce this problem (the first one) from scratch.
But if you cannot, you cannot prove to us that the problem even exists. Too bad...
It's good that you resolved the second one, thanks you for the note.

Perhaps clear out your temp asp.net files folder. Then try regenerating again.
