I have an object where I do 'special' cleanup in case of exception
my code is somewhat like that:

void Method()
{
   try
   {
       Something();
   }
   catch
   {
       SpecialCleanup();
       throw;
   }
   finally
   {
       NormalCleanUp();
   }
}

my problem is that when an exception is thrown VS break into the catch
clause and I have no idea what causes the exception.

I also tried
catch(Exception ex)
{
   SpecialCleanup();
   throw ex;
}

but the ex.StackTrace is reinitialized and I have no idea of the problem!
any tips on how to to be able to debug that?

for now I wrote:
#if !DEBUG
   catch
   {
       SpecialCleanup();
       throw;
   }
#endif

but I would like to catch meaningful stack trace at runtime as well....
