Exceptions should absolutely be a part of an interface and it stops you from leaking implementation details. If I have an IRepository interface then none of the methods should ever throw SqlException, HttpException, or anything like that. You'd map them to something else. Exceptions in most languages are implicitly part of the contract, and not having consistent ones on an interface breaks Liskov's Substitution Principle. |
