Solution 3

It does not solve your problem; just an important side note:

This is functionally correct but pointless:

C#

try {
/...
} catch { //there are no cases when you should catch all and not use an instance of Exception
    Stop();
    throw;
}

Correct pattern is this:

C#

try {
/...
} finally { //finally is specially designed for such cases
    Stop();
}

Unless he doesn't want to Stop() unless the try block fails, if no exception he wants to keep 'it' running?
