Windows 7 includes the .NET Framework 3.5.1 as an OS component.
This means you will get:
However, if you’re using newer versions of .NET, and if you’re using libraries that don’t get shipped with the above, then you still need to consider packaging these up in an MSI/installer.
This page on Wikipedia has a good summary:

If this is anything more than a “quick and dirty” app, or unless you work in an area where you know exactly what the target machines look like (i.e. a corporate environment with a locked down OS image) then I’d suggest you look at building an installer and deal with pulling down the pre-requisites as appropriate. (WiX is my recommended way of doing that).
