Updating an asp.net mvc web application: can I just update a single dll in bin /?

Question

I have an asp.net mvc (1.0) application in production (IIS7.5, W2008), and I need to update one of my data classes.

Is it possible to simply replace an existing DLL with a new one? Do I need to restart IIS, or will it restart automatically?

Answer 1

MVC applications are just custom web applications, so this will work, assuming you don't miss any other changes.

The application itself will "bounce", and some may lose sessions in the process, but it will be downloaded automatically.
