There are times when you want to retrieve the ID of the last inserted record when using Entity Framework. For example:


Employee emp = new Employee();

emp.ID = -1;

emp.Name = "Senthil Kumar B";

emp.Expertise = "ASP.NET MVC"

EmployeeContext context = new EmployeeContext();

context.AddObject(emp);

context.SaveChanges();


In the above example , if i need to retrieve the ID of the employee that was inserted , all that i need to do is use the emp.ID property once the data is saved as shown below.


Employee emp = new Employee();

emp.ID = -1;

emp.Name = "Senthil Kumar B";

emp.Expertise = "ASP.NET MVC"

EmployeeContext context = new EmployeeContext();

context.AddObject(emp);

context.SaveChanges();

int empID = emp.ID;
