Multiple versions of dotnet

[Guest]

If I develop an app in 2.0 and install it on a machine running an existing
app on 1.1, both versions are installed on the machine. Are there any
possibilities of version conflicts between the two apps? Does the 2.0
installation replace any 1.1 files that could cause problems for the 1.1 app?

Multiple versions of .NET framework installation do not replace each other
(i.e. later version of .NET does not replace older version). They can be
installed side by side. App written for each versio of .NET will run using
corresponding .NET framework.

However, app written on older version of .NET would run (may be very few
exceptions, depending what the app does) on computer with later version of
..NET framework only.

Thanks,
I had presumed as much but we've had a number of clients hedging about
allowing 2.0 to be installed. Know of any MS documentation I can use as ammo?

At the time of the first transition (1.0 -> 1.1) they published this:

http://msdn.microsoft.com/netframework/technologyinfo/versioncomparison/default.aspx

Just by the way, it doesn't specifically address the 1.1 to 2.0 change but
rather the fact that unlike the API, multiple versions of the framework can
co-exist.
