What does this error mean 'The element 'Dependent' in namespace has incomplete content

Question

The element 'Dependent' in namespace 'http://schemas.microsoft.com/ado/2008/09/edm' has incomplete content. List of possible elements expected: 'PropertyRef' in namespace 'http://schemas.microsoft.com/ado/2008/09/edm'.

I'm using EF4, db first. The error links to an association within the edmx file, unfortunately I am not very experienced with EF Database First (I have previously been using code first) however this error really does not seem to make much sense anyway.

Answer 1

I am guessing a little here but...try regenerating your edmx?
