Acquire the ID of last inserted row using Entity Framework

Acquiring the ID of last inserted row (Primary and auto increment column) using Entity Framework is as follows:

 
    Entities oEntities = new Entities();
    tblSample ts = new tblSample();
    ts.Description = "some Description Here!!!";
    oEntities.InsertToSample(ts);
    oEntities.SaveChanges();

    lblMessage.Text = ts.SampleID;
