c# - Having trouble getting Entity Framework to savechanges -

first post here bare me.

i have entity framework set create entity object. no exception thrown. when put in break point entity object seems catch data nothing gets committed db.

take look:

        var dbctx = new firsthanddm();//datacontext         var newcontact = new contact();//entity object          newcontact.first_name = firstname.text;         newcontact.last_name = lastname.text;         newcontact.company = companyname.text;         newcontact.phone = phone.text;         newcontact.email = emailaddress.text;          dbctx.contacts.add(newcontact);         dbctx.savechanges(); 

i running entity framework 6.0.
