ASP.NET Deployment: Patches

[ZeroCoolJr]

Hi,

 

This is my first time to handle ASP.NET Web Applications after being drown into Windows Application for months :p.

 

Currently, I have read about XCOPY, Publishing, Web Setup Project, Web Deployment Project and manual installation. I want to know what's the best solution to implement patching Web Apps. That is to the least possible to 0 downtime. I have read about this Application State that dies if I'm going to rewrite a dll that is running, can someone elaborate more about this? Please point me to the right direction.

 

In short, I want to implement a `plug-n-play` architecture. Is it possible?

 

Thanks.
