Just upgrading some of my projects and am going to note some of the breaking changes for anyone else.
ContextOptions.DeferredLoadingEnabled = true;
ContextOptions.LazyLoadingEnabled = false;
It seems the T4 template for the Self Tracking Entities was not updated with this change for the ContextOptions.
Here is the Fix
Just unzip and replace the following files.
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\Code\1033\AdoNetEntityDataModelT4SelfTrackingCodeGenCsharp.zip\EF.SelfTracking.Context.ctp.CS.tt
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\Code\1033\AdoNetEntityDataModelT4PocoCodeGenCSharp.zip\EF.Poco.Context.ctp.CS.tt
When I opened up my Solution with a Workflow project it was unable to open it.
It seems they have now added two new Workflow Project Types.
WCF Workflow Service Application
Workflow Console Application
Also it seems the XAML has changed and the designer can’t interpret old Activities.
Found another bug which I just battled an hour with.
My Custom Activities weren’t showing up in the Workflow toolbox it turns out that they only show up when the Activity Library project is not contained in a Solution folder.
The referenced assembly "DLLName.dll" could not be resolved because it has a dependency on "System.Web, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client".
