    ron_marz, this installer does contain 2.0 SP2 through to 3.5 SP1 inclusive. Although DotNet 1.1 is separate and so will 4.0 be when it's released.

    TGB72, I've used the full installer perfectly fine on computers with no internet connection (it does attempt to check for updates but doesn't throw an error due to no internet connection). My guess is that you had the DotNet 3.5 installer and when it checked for updates it will have downloaded the SP1 bits.

    I do agree that on older computers WPF applications are slow (WinForm apps still seem ok to me), but on newer computers I wouldn't have thought WPF applications were that slow although could still do with some improvement.

    When will they ever release a build containing version 1 through 3.5 inclusive, so we don't have to install every version sequentially to get to the latest one?

    The installation is a nightmare.
    The full redistributable package is around 197MB and it requires to download another 67MB, so it's not so full and can't be installed in PC without connection.
    All the apps that work with .NET run SLOWWWW.
    M$ it have no shame at all launching this crap.

    Thank you Banquo!

    Users ignorant of what the software is just feel they have to comment because it's from 'Microsoft'! Sheesh. Nice to have some intelligent life around here.

    Two thumbs up for this release!!! Much anticipated! The Dynamic Data and AJAX updates will put a smile on my face for a long time to come.... presssents :)
