Same code works fine on my colleague pc... but when I try to save the form on my pc I get the following error.

No, I haven't seen something like that.

However, you might try doing a Clean in your solution. And you might also try deleting the temporary web cache VS creates under your user profile. Sometimes that cache gets old stuff and VS can get confused.
