title: Why does Visual Studio stall while debugging?
body: <p>Sometimes, while I am debugging a c# application, I will hit a break point and when I try to continue, step or step into, it just does nothing.  The yellow line highlighting the current line goes away, but it never reaches the next line.  The app is still frozen like I am on a breakpoint and I can do nothing but hit the stop debugging button and restart.  This doesn't happen all the time, but once it starts on an app it seems like it always happens after that for that app.  I have found that adding the following code just before the class declaration "fixes" the problem for that app, but am very curious as to why this is happening.</p>
  
  <pre><code>[System.Diagnostics.DebuggerDisplay("Form1")]</code></pre>
  
  <p>Additional details:
  I have not noticed any kind of pattern as to what the particular line does when it freezes. Most of the apps I write use threading, so there is a decent chance this is happening within a thread every time.</p>
