A Tale of Two Threads by Casey Watson @ Dallas C# SIG on 02/04/2010

Another in the series of recordings that I have done for INETA Live. Abstract: A user interface, unresponsive, unable to provide feedback to a frustrated user. A complex back-end process, performing intense calculations, consuming every available resource. A single thread, starving for more processor time than the operating system can possibly provide. In a world of multi-core machines, one framework stands above the rest, ready to take advantage of today's modern hardware. It's journey, fraught with peril and danger. It's weapons, an arsenal of synchronization mechanisms. Coming this Thursday, from the makers of quality software,...

Upgrade from SSIS 2005 to 2008 broke SSIS Logging

My DBA upgraded our server from 2005 to 2008 and when it did my SSIS packages stopped logging messages. Problem 1: Well the default logging mechanism in 2005 logs to the dbo.sysdtslog90 table. Well in 2008 they changed the table name to dbo.sysssislog. Not a big deal, but you will never find something if you look in the wrong place. Problem 2: Well now that I am looking at the right table, I noticed that my events were NOT showing up. In particular I was looking for the OnPreExecute and OnPostExecute methods. Poof gone, after many searches I stumbled across the following posts: Ahh,...
