When I generate Entities using the POCO template I get objects based on ObjectContext. The generated entities have navigation properties that follow the pattern of:
Code: Select all
/// <summary>
/// There are no comments for MyItems in the schema.
/// </summary>
public virtual ICollection<MyItem> MyItems
{
get
{
if (_MyItems == null)
{
var newCollection = new FixupCollection<MyItem>();
newCollection.CollectionChanged += FixupMyItems;
_MyItems = newCollection;
}
return _MyItems;
}
set
{
if (!ReferenceEquals(_MyItems, value))
{
var previousValue = _MyItems as FixupCollection<MyItem>;
if (previousValue != null)
{
previousValue.CollectionChanged -= FixupMyItems;
}
_MyItems = value;
var newValue = value as FixupCollection<MyItem>;
if (newValue != null)
{
newValue.CollectionChanged += FixupMyItems;
}
}
}
}
private ICollection<MyItem> _MyItems;
private void FixupMyItems(object sender, NotifyCollectionChangedEventArgs e)
{
if (e.NewItems != null)
{
foreach (MyItem item in e.NewItems)
{
item.ProductVersion = this;
}
}
if (e.OldItems != null)
{
foreach (MyItem item in e.OldItems)
{
if (ReferenceEquals(item.MyParent, this))
{
item.MyParent = null;
}
}
}
}
But if I use the DbContext template, then the navigation properties have a pattern of:
Code: Select all
/// <summary>
/// There are no comments for MyItems in the schema.
/// </summary>
public virtual ICollection<MyItem> MyItems
{
get;
set;
}
Code: Select all
MyParent p = new MyParent() { Name = "Some Name" };
MyDbContext.Parents.Add(p);
p.MyItems.Add(new MyItem() { Quantity = 8} );
