    {
        return this._Products;
    }
    set
    {
        this._Products.Assign(value);
    }
}

<Association(Name:="FK_Products_Categories", Storage:="_Products", OtherKey:="CategoryID", DeleteRule:="NO ACTION")>  _
Public Property Products() As EntitySet(Of Product)
    Get
        Return Me._Products
    End Get
    Set
        Me._Products.Assign(value)
    End Set
End Property

Remarks

If set to null, no delete behavior is added. For example, "CASCADE" would add "ON DELETE CASCADE" to the foreign-key relationship.

In the following example, the rule is to take no action.
