Still a problem 10/27/2013
Windows 7 Enterprise SP1 (64bit)
Visual Studio Ultimte 2012 v11.0.60610.01 Update 3
CRM 2011 SDK 5.0.17
Microsoft Dynamics CRM 2011 Update Rollup 15 (5.0.9690.3731) (DB 5.0.9690.3557)
Referencing .dlls manually does not solve the issue.
Windows desktop search of the entire local drive for "workflowdesigner.xaml" does not yield any results.
All project files are on the local drive.
Does anyone know of a workaround or the location to download a previous working version of the SDK?
