Will .NET 2 application work on .NET 3?

If I program an application designed for .NET 2 and then a computer with only .NET 3 installed launch the application - will it work?

I know there are some significant changes between the frameworks, such as obsolete methods and for example new features like LINQ (was it only 3.5?).

What if I have tested the code with .NET 3 and it works?

To describe what my situation is: I have both .NET 2 and .NET 3 on my PC - there are absolutely no problems when I click on "projects -> settings -> .NET 2" and then startwithoutdebugging. There are also absolutely no problems when i do projects -> settings -> .NET 3 and then start the app without debugging.

I just want to be sure that my application will run on any machine that has .NET >= 2.0.

.net 3.0 is basically .net 2.0 plus service pack plus some libraries.

The extra libraries won't hurt, but there are changes in the service pack; you could in theory hit an edge case that makes it not work. So test it.

But usually you are fine.

Everything from 2.0 to 3.5 runs on top of the same version of the .NET run-time so yes, your application will be fine.
