title: Visual Studio 2010 Bug?
body: <p>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:
  <img src="https://i.stack.imgur.com/akQjT.png" alt="enter image description here"></p>
  
  <p>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.</p>
