I would like to clean-up some of my computers. There are multiple versions of the .NET framework installed in parallel (2.0, 3.0, 3.5). How can I find out if one of my local applications is still using these frameworks? And how can I find out which applications are using it?

You can't, because there's nothing to say an application has to register with .NET or anything. It just uses it - the application doesn't even need to be installed.

Besides which - having multiple version of .NET is absolutely fine.

  • OK. So is there a way to tell that a running application is using a specific .NET version? Like "command X shows it has loaded Y.dll so it uses .NET 3.5".
