How to submit changes in LinqPad

If you are using an EF Context, then you need to call SaveChanges()

If you are using a Linq2Sql context, then you need to call SubmitChanges()

Change Language in LINQPad to "C# Program" and use the following code

void Main()
{
    var p1 = Person.Single(x => x.Id == 1);
    p1.Name = "Test";
    SubmitChanges();
}
