Visual Studio 2010 Bug? - visual-studio

Question

I'm not a bug expert hence y'all shouldn't yell at me if what I am about to say isn't what I should be saying. Here is the situation. I'm building a desktop windows form application in C# using VS 2010 Ultimatum. I added a new user control which contains a picture box that should display an image when some PropertyChangedEventHandler is fired. The application itself works as expected: No compilation error and when I run it, it does what it was meant to do. However VS is acting weird. Indeed, when I open the project in VS, it gives me this message:
I thought maybe my VS installation is corrupted. I reinstalled it, and opened the project again but the same happens. Strangely, if I comment out some code that invoke the PropertyChangedEventHandler , then VS would start and work normally. Is this supposed to be a VS bug? After all, it should at least complain that my code isn't supported but it shouldn't crash just because I wrote some bad code. Besides, if my code compiles and works as expected, can someone please tell me what's wrong?
P.S: Below is the details of the error as shown by VS. I'm looking to hear what you think.

You need to disable PropertyChangedEventHandler from firing in Design mode.
If this is C#, it should look like this:
if(!this.DesignMode)
{
PropertyChanged(this, e);
}
If not that specifically, then disable whatever features might be causing the error from triggering in DesignMode.
