A string representing the rule.

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.

	[Association(Name="FK_Products_Categories", Storage="_Products", OtherKey="CategoryID", DeleteRule="NO ACTION")]
	public EntitySet<Product> Products
	{
		get
		{
			return this._Products;
		}
		set
		{
			this._Products.Assign(value);
		}
	}
