Trying to update System.Windows.Controls.Data.dll to the December release. I've followed these instructions from Microsoft:

To install the Silverlight 2 DataGrid December 2008 Release:
  1. Close all instances of Microsoft Visual Studio.
  2. Delete all cached toolbox items by removing all files beginning with "toolbox" from %LocalAppData%\Microsoft\VisualStudio\9.0.
    • On Microsoft Windows XP, %LocalAppData% is Documents and Settings\UserName\Local Settings\Application Data.
    • On Microsoft Windows Vista, %LocalAppData% is Users\UserName\AppData\Local.
  3. Replace the following assemblies with the ones in this package:
    • %ProgramFiles%\Microsoft SDKs\Silverlight\v2.0\Libraries\Client\System.Windows.Controls.Data.dll
    • %ProgramFiles%\Microsoft SDKs\Silverlight\v2.0\Libraries\Client\System.Windows.Controls.Data.Design.dll
  4. For any existing projects, delete the reference to System.Windows.Controls.Data.dll and then re-add the reference.

All appears to compile and run. When I try to load the datagrid with data I get the following error:

System.IO.FileNotFoundException was unhandled by user code
  Message="Could not load file or assembly 'System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

       at IdeaBlade.EntityModel.v4.DataEntityProperty`2.GetValue(TInstance instance)
       at DomainModel.Customer.get_CompanyName()
  InnerException:
This happens in the Devforce samples as well. I've verified that the file (System.Windows.Controls.Data.dll) is contained in the XAP. This error happens in the DevForce DomainModel Designer file.
 
Any ideas? Thanks in advance for your help.

The Silverlight bits of DevForce 4.3.0.1 were built against the "standard" Silverlight 2 tools released in October 2008.  It looks like Microsoft did not make the old assemblies and the December DataGrid release version compatible.  DevForce is compiled against:
 
   System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
 
While the assembly in the December release is named:
 
   System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=3d8c6023c75a3242
 
So, the assemblies were signed differently and the names don't match. 
 
I don't know a workaround for this.  I doubt that assembly binding redirection works in SL, and I don't know a way to add multiple parts with the same short name to the SL assembly manifest.  We will research this further to see if we can address this problem, but for now DevForce 4.3.0.1 works only with the October SL 2 bits.  (For the record, DevForce Silverlight 5.0.0.x uses Silverlight 3 Beta 1.)
