Schema specified is not valid. Errors: The relationship was not loaded because the type is not available

Question

I wish to reference the OrderAddress model twice in my Order model; once as a ShippingAddress and once as a Billing

Answer 1

I got the same error using database first: "The relationship was not loaded because the type ... is not available". The problem was the model in the solution was outdated. To fix the problem:

• Double click on edmx file under Solution.
• Right click on it.
• Select "Update Model from Database...".
• Click on the "Refresh" tab.
• Click on the Finish button.

Your edmx now should be updated with the latest database changes.
