EntityFramework exec proc with out params

using (var db = new MyEntities())
{
    var Owner_ID = new ObjectParameter("Owner_ID", typeof(string));
    var msgError = new ObjectParameter("msgError", typeof(string));
    db.InsBeerClient(Owner_ID, msgError);
    return (msgError.Value ?? "").ToString();
}

Entity Framework Update

You can easly do it by using this code

using (var db = new EGAIS_RUEntities())
            {
                db.Configuration.ValidateOnSaveEnabled = false;
                var _rec = new CONTRAGENT()
                {
                    id = 1,
                    status = 3
                };

                db.CONTRAGENTS.Attach(_rec);
                var entry = db.Entry(_rec);
                entry.Property(e => e.status).IsModified = true;
                db.SaveChanges();
            }

Please note, I set only value, that i wanted to cahnge. Another value is "id", that identifies the record.

Another interesting aspect is this

db.Configuration.ValidateOnSaveEnabled = false;

You will get an error if you don't set the fields with NOTNULL values.

another approach to it is

dbcontext.Entry(_rec).State = System.Data.Entity.EntityState.Modified;
dbcontext.SaveChanges();
