Commented Unassigned: Can't open EDMX after creation - throws Exception [11985]

I add edmx to the project: "Add Entity Data Model (EDMX) to current Project..."

If i try to open the created edmx in VS2013 it throws an exception: 'Exception has been thrown by the target of an invocation.'

I make a video of the whole process:

How can i add an EDMX Model from an SQLCompact Database 4.0 to VS2013 Ultimate?


Versions: VS2013 Ultimate & SQL Server Compact/SQLite Toolbox Version 4.1.6.0

Have you tried install the latest EF Tools and simply using the EDM Wizard?
