A quick lesson for today. To rethrow an exception in C#, you do NOT

catch(Exception ex)
{
    // do something
    throw ex;
}

This creates a new Exception Object because throw is followed by an expression. The simple and sexy way intended by C#:

catch (Exception ex)
{
    // do something
    throw;
}
