Finding the reason for DBUpdateException

by

This is my override of SaveChanges. It gives me a useful place to put breakpoints:

    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException e)
        {
            foreach (var eve in e.EntityValidationErrors)
            {
                Debug.WriteLine(@"Entity of type ""{0}"" in state ""{1}"" 
                   has the following validation errors:",
                    eve.Entry.Entity.GetType().Name, 
                    eve.Entry.State);
                foreach (var ve in eve.ValidationErrors)
                {
                    Debug.WriteLine(@"- Property: ""{0}"", Error: ""{1}""",
                        ve.PropertyName, ve.ErrorMessage);
                }
            }
            throw;
        }
        catch(DbUpdateException e)
        {
           //Add your code to inspect the inner exception and/or
           //e.Entries here.
           //Or just use the debugger.
           //Added this catch (after the comments below) to make it more obvious 
           //how this code might help this specific problem
        }
        catch (Exception e)
        {
            Debug.WriteLine(e.Message);
            throw;
        }
    }
