title: visual studio 2010 unable to start program .dll
body: <p>I have a problem for my visual studio 2010. When I click start debugging button and it's start debugging. </p>
  
  <p>It seems that there is no error "i just create one "button" on it "</p>
  
  <p>But it will show <code>Unable to start program 'c:\users\.....\xx.dll'</code></p>
  
  <p>Does someone now how to solve it?</p>
  
  <p>The second question is: when I click left button to see the "Button" source code,
  why it will show all this project code? Should I revise some setting?</p>
