TFS2010 with VS2012 workflow build process templates-Collection of common programming errors

It’s known that Visual Studio 2010 works extremely slow with build process templates using Visual Designer for editing the XAML file (more info at: Why is the Workflow Designer so extremely slow when editing build process templates?). For this reason, I started to use Visual Studio 2012 with very good results. Each file saving takes 2 seconds instead of the 40 I got with Visual Studio 2010. In order to make it work, I had to clean-up versioned assemblies and change my custom ones to .NET 4.5 framework.

Once I got everything sorted out (load the workflow in the Visual Designer without errors), I launched a build definition with that workflow against our TFS2010 server and I got the next error message:

TF215097: An error occurred while initializing a build for build definition \MyProject\MyBuildDefinition: Cannot set unknown member ‘{http://schemas.microsoft.com/netfx/2009/xaml/activities}TextExpression.NamespacesForImplementation’.

Is it possible to run VS2012 edited build templates in a TFS2010? If so, how can I resolve that issue?

I tried the following blog suggestions with no results.
