MS CRM 4.0 workflow assembly in a MS CRM 2011 solution

Just got this error when uploading a crm 4.0 workflow assembly in a CRM 2011.
Could not load file or assembly ‘Microsoft.Crm.Sdk, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35′ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0×80131040)
Found the solution at Rick Wilson blog link
Just add this after the configSections section in the web.config of the CRM 2011 website.
<assemblyBinding xmlns=”urn:schemas-microsoft-com:asm.v1″>
<assemblyIdentity name=”Microsoft.Crm.Sdk” culture=”neutral” publicKeyToken=”31bf3856ad364e35″ />
<bindingRedirect oldVersion=”″ newVersion=”″ />
