multiple versions of MSframework installed RRS feed

  • Question

  • Automatic updates has installed 3 versions of .net framework, 2.0, 3.0, and 3.5 and they show up in my control panel.  Do I need all 3 copies or can I uninstall 2.0 and 3.0 and not give my computer problems.  Also let me say I haven't a clue what this program does or if I need it.

  • Hi Gpedens,

    Referring to removal of the .NET Framework, it depends on the applications and OS that are ran on your PC.

    If you need .NET Framework 3.5 on your PC, .NET Framework 2.0 and 3.0 cannot be removed because .NET Framework 2.0 and .NET Framework 3.0 are the prerequisite of .NET Framework 3.5. So the three .NET Frameworks cannot be removed.
    All versions of the .NET Framework from 2.0 onwards (i.e. 3.0 and 3.5) use exactly the same core framework files. The CLR is still v2.0 which is the core in .NET Framework 2.0. The Core parts are referred to speak as the 'Red Bits' and the rest as the 'Green Bits'.
    For more information, see: http://www.danielmoth.com/Blog/2007/06/net-framework-35.html
    If you're not sure whether you need them for applications or OS, I also suggest you to keep all the versions.

    Thanks

  • These are .net frameworks (http://en.wikipedia.org/wiki/.NET_Framework)  for executing .net applications on your computer. You can keep all the versions as .net applications developed on 2.0 will need 2.0 framework,3.0 will need 3.0 framework and so on.
