Entity Framework doesn't save new record into database

Question

Hy,
I have problem with saving new record into database using Entity Framework.
When I run program, everything seems normal, without errors . Program shows existing, manually added records into the database, and new one too. But new one isn't save into database after running program.
I've got no idea where's problem. There is code for add new record, show existing.
Thanks for help!!
// add new record
using (var db=new DatabaseEntitiesContext())
var person = new Table()
First_Name = "New_FName",
Second_Name = "New_SName",
PIN = "4569"
db.Tables.Add(person);
db.SaveChanges();
//show all records
using (var db=new DatabaseEntitiesContext())
var selected = from x in db.Tables
select x;
foreach (var table in selected)
Console.WriteLine("{0}{1}{2}",table.First_Name,table.Second_Name,table.PIN);

Hi BownieCross;
If you are using a local database file in your project the following may be the cause.
From Microsoft Documentation:
Issue:
"Every time I test my application and modify data, my changes are gone the next time I run my application."
Explanation:
The value of the Copy
to Output Directory property is Copy
if newer or Copy
always. The database in your output folder (the database that’s being modified when you test your application) is overwritten every
time that you build your project. For more information, see How
to: Manage Local Data Files in Your Project.
