What's the use of attributes on an interface?

Question

Using Resharper, I extracted an interface of an existing class. This class has some attributes set on a few members, and Resharper also put these on the interface members.

Can I delete these attributes from the interface? Attributes on an interface aren't inherited when implementing an interface right?

Answer 1

They aren't used by the implementing class - but still might be critical. For example, WCF defines service-contracts and operation-contracts by the attributes on the interface.

If they aren't of use in your case, then delete them. Otherwise, leave them alone ;-p
