    .net framwork 4

    If i install .net framework 4, do i really need all the previous versions? Im not sure its backward compatible for applications that need earlier versions, ie: 2, 3, 3.5 etc.

    Many Thanks

    As far as I am aware it's not a case of backward compatibility, they are effectively different things. That's why when you install a new one, the older ones don't disappear.

    Correct.... a newer version doesnt replace a previous version so you will indeed require the older versions (think most apps using .net framework are probably still using .net 2.0 or 3.x).

    Windows 7 already includes v3.5 SP1, v3.0 SP2 and v2.0 SP2, so you would only need to install v4.0.

    I would ignore v1.0 & v1.1 unless you have applications which specifically need it.

    I'm interested to know what the current baseline seems to be. All of the applications I'm actively developing target .NET 3.5 or lower, simply because they'll work on Windows 7 without any extra dependencies. Has anyone actively deployed v4.0 yet?

    Yep, I'm developing with it at the moment for one of our systems.
