Importing C# code ???

[Ed]

I’m importing a large C# project with many business entities.
When I view the generated class diagram is does not contain any association links/connectors.
In several cases a given class is associated with another class that is placed right next to the first class on the diagram but no association connector appears on the diagram.
When I view a given class and the Links tab these associations are missing.
The code was imported correctly, so I think, since when I look at the class properties I see all the associations.

Any ideas?

Thanks,
Ed
