Referenced table is not coming in my model through entity framework 5.0

Recently i have resolved my issue, problem was i had a main table which has a primary key, and that primary key was mapped with my missing table's column in that column i set "Allow null", as i changed "Allow not null", and update my data model from Entity framework 5.0, it was visible in my solution.

Thank you for all suggestions.

make sure you have "not null" in the declaration of FK

I had this problem, in my case I didn't have created the primary key to my table, so I just set it and I could update my EDMX.
