The initial release of Microsoft Dynamics CRM SDK 4.0.10 contained an incorrect assembly in the SDK\Bin folder. This has been corrected.
Please visit the download page to refresh your copy:
The only change to this download package is the contents of the SDK\Bin folder. The readme has been updated to indicate this change.
Look for this notice:
“November 10, 2009 – Updated the assemblies in the Bin folder. Use these updated assemblies instead of the ones in the previous release of SDK 4.0.10.â€?
This may take a few hours to propagate across all of the MSDN servers but should be available by Wednesday.
