I want to define a Foreign Key for one column in two Tables.

I am working in VWD 2010.

I tried "SELECT * FROM Employees INNER JOIN Departments ON (Employees.DepartmentID = Departments.ID);

That worked but when I add "ADO.net Entity Data Model" it did not show the Foreign Key Bridge between the two tables.

How do I get that bridge?

Selecting from a pair of tables does not define a foreign key. How have you defined the foreign key?

I agree with @CHill60, You have to add foreign key constraint in table by adding relationship between Employees and Department table, then update model from database.

You need to do some research on Foreign Key Contraints[^]
Something like this might work

SQL

ALTER TABLE Employees
ADD CONSTRAINT FK_Department FOREIGN KEY (DepartmentID)
    REFERENCES Departments (ID) ;
