Does C# solve the problem of swallowed exceptions?
No. In fact, C# requires it! Methods in C# cannot specify the exceptions it may throw. The documentation of the method you wish to call may mention the list of exceptions you can expect. But this list of exceptions is not enforced by the compiler, and is not guaranteed to be exhaustive. Also, since the list of exceptions is not part of the contract, the method can be revised at any time and a new exception that you didn’t know about can be thrown. Since there is no previously agreed upon list of exceptions, you are left with no option but to catch all exceptions if you want to recover from an exception (such as by offering to connect to an alternate database if the primary database is down, etc.) Obviously, if you catch all exceptions, you will end up swallowing some of them.
