title: Mixed mode debugging asp.net applications
body: <p>I have an asp.net application and can debug the application fine when I click F5 (Start Debugging), hits breakpoints, no problem. When I have a web app open and I try to attach to the w3wp.exe process, I get a message saying "Unable to attach to the process.  Mixed mode debugging is not supported on Windows 64-bit platforms."  Is there a way for me to attach to the process?</p>
  
  <p>My asp.net application is .net 3.5, has a platform target specified as "Any CPU", and the Configuration set to debug.  I am developing on Win7 x64 bit system.</p>
