I recently ran into few cases where customer needed to automate SSIS Project configuration and job creation and I had search whole web to finally reach somewhere.
I think it would be nice to have whole procedure documented so others do not have to search extensively to achieve this.
Also I have created C# code as well as Powershell code to do same so that one can choose what he want to do.
C# and Powershell are kind of similar but It was first time I was trying something powershell so took some time.
I had posed this on my team blog so i will just give references to those blog posts, let me know if you guys have any comments.
