title: Silverlight 3 debugging issue and intellesense issue
body: <p>I am pretty new to Silverlight 3.0.</p>
  
  <p>I have installed <strong>Silverlight 3 Developer</strong> on Visual Studio 2008 SP1; and later on I came to know that I have to install <strong>Silverlight3_Tools.exe</strong>.</p>
  
  <p>Hence, I have uninstalled <strong>Silverlight Developer</strong> and installed <strong>Silverlight3_Tools.exe</strong>.</p>
  
  <p>From then onwards I am facing lot of problems with Silverlight in my development box.</p>
  
  <p><strong>The most killing problems are these two below</strong></p>
  
  <ul>
  <li><p>Whenever I run the application in Debug mode I get the following error:</p></li>
  </ul>
  
  <p><strong>Unable to start debugging. The Silverlight managed debugging package isn't installed.</strong></p>
  
  <ul>
  <li>While working with code editor in Silverlight, intellesence is not working. Whatever the installation I have done (VS-2008SP1 and Silverlight3_Tools.exe) I have given the same to colleagues. Everything is working fine for them.</li>
  </ul>
  
  <p>Hence, above two problems are killing me and stopping me to go ahead.</p>
  
  <p>Can anybody please help me.</p>
  
  <p>Thanks in advance...</p>
