243 - Return from a finally-block halts global unwind.
Consequence: The exception will not be propagated.

This warning indicates that a return statement was detected in the handler of a try/finally statement.

A try/finally statement is intended to allow guaranteed cleanup, not exception handling, but returning from the finally block will handle an exception if one occurred.

Example
