Remarks

You apply the DeleteAttribute attribute to a method to indicate that the method is a delete method. If your method matches the expected method signature for a delete method, you do not have to apply the DeleteAttribute. The RIA Services framework will infer that a method with the expected delete signature should be treated as a delete operation. You apply the IgnoreAttribute to a method to prevent the RIA Services framework from generating a domain operation for that method.

The following shows the expected signature for a delete method:

Return value	None
Parameters	Entity
Name Prefix	Delete or Remove
Attribute	[Delete] (C#) -or- <Delete()> (Visual Basic)
Example	public void DeleteProduct(Product product) (C#) -or- Public Sub DeleteProduct(ByVal product As Product) (Visual Basic)

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
