.NET Framework 2.0 to 3.0

[r.manikandan]

These different versions of frameworks which seems quite too many for
me, do they provide any sort of downward compatibility. I mean can I
assume that if I write a application on .net framework 2.0 will it work
okay when I move to 3.0 ? Or do I need to do some sort of conversion?

Is anyone have any personal experiences. I know that if we have to
make use of new features we need to probably re-write some part of the
applications, but when I really don't want to make any tangible changes
to one of my application and still want to run it on the next framework
version will it work ? Especially from 2.0 to 3.0.?

Well, 3.0 isn't a real new version of the framework. Its pretty much
..Net 2 + WinFX assemblies. So if you make an application in 2.0, it
will run perfectly fine on 3.0. This is more or less true of all
versions; if you target 1.1, it should run fine on 2.0 or 3.0 or 4.0.
Of course to be sure you'll have to test and check to see if there are
any breaking changes from each version of the framework.

The .NET framework 3.0 is the .NET framework 2.0 plus additional
libraries. The compiler is the same. There is no conversion needed. If
you want to do Windows Presentation Foundation, Windows Communication
Foundation, Windows Workflow Foundation or Cardspace, you install the
framework 2.0 and then you install the framework 3.0 on top of that.

HTH,

From 2.0 to 3.0, you should be fine. Same with backwards compatibility,
except if you use some of the new features. You should compile the final
release in the version of the Framework you are targeting for deployment.

Thanks guys for your replies..

Is (re)compiling necessary when I am not changing my code at all for
each version of framework?

Cheers,
Mani.
