Question

I know that this is redundant (per Why does resharper say 'Catch clause with single 'throw' statement is redundant'?).

try
{
    bla bla bla
}
catch
{
    throw
}

So, I’m going through the old Microsoft Membership and Role Provider code (made available since 2006 per http://weblogs.asp.net/scottgu/archive/2006/04/13/442772.aspx). And, low and behold, the code is chock full of this redundant code.

Was there a good reason?

Answer 1

This is a lazy way to put a breakpoint on that throw line, without turning on any of the debugger features that break on all exceptions.
