GetWinFXPath task could not be loadedPermalink

I recently ran into this issue and couldn't find much info on it so I thought i'd post it in case someone else had the same problem.  While trying to build my project(targeting .NET 3.5/C#) in Visual Studio I got the following error:

The "Microsoft.Build.Tasks.Windows.GetWinFXPath" task could not be loaded from the assembly
PresentationBuildTasks, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35.
Could not load file or assembly 'PresentationBuildTasks, Version=3.0.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the 
file specified. Confirm that the  declaration is correct, and that the assembly and all 
its dependencies are available.

There were no other errors listed and it worked the day before.  A little digging and I found that .NET 3.0 had somehow been disabled.  To fix it I just had to re-enable it.  These steps apply to Windows Vista, but i'm sure would work in Windows XP as well, but by going a different route.

  • Go to your Control Panel and click "Programs and Features"
  • Click "Turn Windows features on or off" on the left panel(Kicks in UAC if it's enabled)
  • Find "Microsoft .NET Framework 3.0" and expand it
  • Check off at least XPS Viewer and click "OK".
  • Close P&F and CP.  If Visual Studio or Visual Web Developer is open, close and reopen it, and reubild your project.  The error should disappear.

File Expression 0.9.3 ReleasePermalink

File Expression 0.9.3 is now available to download.  This is just a minor bug fix.


File Expression v0.9.3
  • FIX: Crash after only deleting a pattern and not adding at least one new one to replace it.

In addition to that, the site is almost fully functional.  I've added alot behind the scenes and am pretty happy with how it's turned out.  It's not really anything you'll notice right away, but i've been building a framework for various features so when then time comes, the changes i'll make will be easier and the transition won't be so rough.
