Let\'s suppose that we have this situation:
Tables in database:
Country (id, country_name), Person (id, login), CountryManager (id_country, id_person), Cou
In VS you can do this with the GUI.
If you show Model Browser then navigate down the tree to:
YourEntityModel > Entity Types > Country
then right-click on the "Person1" Navigation Property and select "Properties" you can then change the name of the navigation property name to whatever you like:
Just change the name, save changes and your done...
(Actually there are lots of ways to get to the Navigation Property properties window - you cn right click on it in the model diagram too)
