Commented Issue: DataForm won't work in Silverlight 5 [8797]

Reproduction:

1. Create a Silverlight project
2. Turn it to version 5
3. Add references to the Silverlight Toolkit (using NuGet or direct)
4. Add a DataForm to your page
5. This is the exception the DataForm constructor throws:

{System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Controls.Data.Input, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
[IO.FileName_Name]
Arguments: System.Windows.Controls.Data.Input, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.0.60401.00&File=mscorlib.dll&Key=IO.FileName_Name
at System.Windows.Controls.DataForm..ctor()}

6. Turn it back to Silverlight 4
7. Now everything works cool

Any ideas?? Workaround??

Hi Jeff,
Silverlight 5 is now RTM.
Today (01/01/12) I referenced the project using NuGet and got that nasty exception. The workaround didn't work.
I think this issue should be taken care of rather than "Closing - a build of the tk for SL 5 should address this issue". If NuGet is made to rely on, this issue should be treated with care.

Thanks
