I created a project using vs2012 with the entity framework. The 3 month trial ran out and I am going back to 2010. When I try to run my project, I am getting this error.
In my gac, I see system.data.entity v3.5.30729.5420
This seems related to this post, but not exactly: Can anyone spot why I keep getting this error testing the EF 5 beta
I uninstalled and reinstalled the nuget package Method not found: 'Void System.Data.Objects.ObjectContextOptions.set_UseConsistentNullReferenceBehavior(Boolean)'.
