Hello,
I have a project that I built in c# on the 2.0 framework.
how can I know if the project will work on the 1.1 or 1.0 framework?
is there a way to make it work on computers that have the other frameworks
installed?
thanks!!!
:wave:

It won't work, guaranteed. Nothing compiled against version 2.0 will work without version 2.0 present on the machine it's being run on. The majority of applications compiled against version 1.0 will work with versions 1.1 and 2.0, and likewise the majority of applications compiled against version 1.1 will work on version 2.0. Microsoft provides a list of breaking changes in each version, so if none of the things listed applies to your app then it will work on later versions of the Framework. There is no reason for this to be an issue though because there is no reason that you can't have all three versions of the Framework installed on the one machine, guaranteeing that all apps will run.Quote:

Every project developed in VS 2005 is compiled against version 2.0 of the Framework. They don't know or care about any previous version of the Framework. If version 2.0 is not present they will not work.
Every project developed in VS.NET 2002 is compiled against version 1.0 of the Framework. If version 1.0 is present on the machine on which they run then they will use it. If it is not present and version 1.1 is then they will use it. If only version 2.0 is present then they will use it. The majority of projects developed in VS.NET 2002 will work on later versions of the Framework but some will not. Microsoft has a list of breaking changes available on MSDN.
Projects developed on VS.NET 2003 target version 1.1 of the Framework by default, but you can change the project settings so that they target version 1.0 or both 1.0 and 1.1. Any project compiled against version 1.1 only will not work if only version 1.0 is present. Most projects compiled against version 1.1 will work if only version 2.0 is present but some will not. Microsoft has a list of breaking changes available on MSDN.
How do I know all this? I read it on MSDN. Microsoft don't keep things like this a secret.
To sum up, the only way to make an app work on all three versuons of the Framework is to develop it in either VS.NET 2002 or VS.NET 2003 with the option to compile against version 1.0 set, then read the lists of breaking changes for versions 1.1 and 2.0 to make sure your code won't be affected by any of them, then test your app on a machine with just version 1.1 installed, then test your app on a machine with just version 2.0 installed, then hope like h*ll that you didn't miss anything importatnt in your testing.
@jmcilhinney,
How they are doing this in SharpDevelop ? Isn't it completely written in C# ? :confused:
SharpDevelop would have been written using the .NET Framework SDK 2.0, so to run SharpDevelop 2.0 you need the Framework 2.0. If it can create apps that target version 1.1 or version 2.0 then obviously it has a compiler for version 1.1 and 2.0, just like VS.NET 2003 has a compiler for version 1.0 and 1.1. You still needed version 1.1 to run VS.NET 2003 though. Microsoft have chosen to support only version 2.0 in VS 2005. Presumably you must choose which Framework version to support when you create a project in SharpDevelop because the version 2.0 languages have changed and so has the Framework. If you want to support version 1.1 then there are a great many things that are not available to you.
SharpDevelop2 is for .Net 2 where as SharpDevelop is for 1.0/1.1
Not according to the download page. It says that SharpDevelop 2 was compiled against .NET 2.0 but can also be used to develop .NET 1.1 apps, while SharpDevelop 1.1 was compiled against .NET 1.1 and could create only .NET 1.1 apps.Quote:
