  Not possible to debug ASP.NET MVC project

Status in “monodevelop” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: monodevelop

  It is not possible to set breakpoints when debugging a ASP.NET MVC
  project

  Steps to reproduce:
  1. Create a new ASP.NET MVC project solution
  2. Press F5 to run in debug mode
  3. Wait until test page loads in browser
  4. Open HomeController.cs
  5. Set breakpoint on line 16 "ViewData["Message"] = "Welcome to ASP.NET MVC on Mono!";"

  Result:
  Monodevelop exception dialog:
  Mono.Debugger.TargetMemoryException: Cannot read 4 bytes from target memory at address 0xffffffff

  If you start monodevelop from a terminal window you will see log warnings about missing .mdb files, xsp2.exe.mdb etc. I cant find these files anywhere, i have tried apt-file and the package content search web service. Should they exist?
