I have developed an app using C# in VS2003. However, when attempting to install the app on another machine that has .NET framework V2.0 installed I get an error saying that the install needs .NET V1.1. Does V2.0 framework not work with prior apps developed on V1.1 Must I downgrade to V1.1 to run my app on the new machine

Does .NET V2.0 Framework work with app built with VS2003?

It is perfectly acceptable, and common to run both Frameworks side by side.
So yes, you must have V1.1 of the framework to run V1.x programs...

Well, in a general sense, yes, you'll have to develop programs for framework 2.0 on vs2005. But you don't exactly need 2005 for building programs. You see, its just an IDE. The whole functionality rests in the framework, that you can easily install on your system, and which doesnt cost anything.
Look around, and you might end up using "csc.exe"!
