I would like to upgrade my web projects on an IIS 5 server from .NET 2.0 to .NET 3.5. These web applications live on a server with other web applications that will not be upgraded to .NET 3.5. The server administrator is reluctant to install .NET 3.5 because he is afraid it will break the applications on that machine that are running 2.0 and 1.1.
As far as I know this WON’T be a problem since .NET 3.5 is an addition to 2.0 more than it is a new Framework. I would like the communities help gathering evidence to show him that their concerns are moot and it won’t hurt the other applications.
Thanks in advance.
If you have .NET 2 SP1 you shouldn’t have a problem.
To be exact .NET 3 & 3.5 are built on top of .NET 2.0 SP 1, we had a problem deploying 3.5 onto a server which only had .NET 2 (not SP1) and it caused the apps on there to break. The reason is your core framework assemblies in .NET 2 are upgraded and have new version numbers which the app wasn’t compiled against.
