The Microsoft .NET Framework 4 was released just a few days ago along with Visual Studio 2010. The framework is currently only available for download but will likely be integrated into upcoming Microsoft operating system releases and updates.

The newest iteration of the framework improves on the current ones. It introduces several new features as well as performance improvements that both developers and end users will benefit from.

Some of the more important changes are:

  • Performance improvement including better processor multi-core support, background garbage collection, and profiler attach on server.
  • Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.
  • Added support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
  • Improvements in performance and scalability.
  • Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.

A full list of changes is available on this Microsoft page.

Microsoft is giving more weight to the web installer in their announcements, and did not mention a standalone installer for the new version of the framework at all in the announcement.

The standalone installer does not require an Internet connection during installation. That's useful as it does away with any connectivity related issues during installation.

Here are the links to both the offline and online installer of the .net Framework 4.

The standalone installer has a size of 48 Megabytes and contains all the files needed to install the new framework which means it does not have to load additional components from the Internet; Ideal for installing the Microsoft .NET Framework 4 on offline computer systems with no direct Internet connection.

The web installer weights in at less than 1 Megabyte but requires an Internet connection to download the remaining components during installation.

Both links point to the English version of the .net Framework 4.

Microsoft .NET Framework 4 requires at least Windows XP SP3, Windows Vista SP1 and will run on both 32-bit and 64-bit editions of those operating systems.

Applications that require the Microsoft .net Framework 4.0 will - as usual - trigger a download of the component if it is not already installed on the user's PC.

    how to download NET Framework 4

    Thank you, I will soon download the standalone version !

    Since a while I am trying to download all the standalone versions of all the different versions of .NET Framework (1.0, 1.1, 2.0, 3.0, 3.5 and now 4.0), with all their SP packages and security updates.

    I am now using XP Home version and I would like to keep it for the future with all the .NET Frameworks included in it : for that I would like to use nLite to put all these together.

    My concerns about this subject are these :


    1- Which files do I really have to install in order to have the latest of each .NET Framework version ?

    For example, the latest version of 3.0 is SP2; do I have first to install 3.0 before installing SP2 or to install SP1 before SP2 ? My opinion is that I must first install 3.0 and SP2 right after without installing SP1, but I just want to check with other people if I am right.

    I would like to know the way to proceed for each version, from 1.0 up to 3.5…

    2- Is that possible to achieve all this without having to deal with files which will ask for additional downloading from internet when we install them ?

    For example, “.NET Framework 3.0 SP1”, “.NET Framework 3.5” and “.NET Framework 3.5 SP1” are asking for an internet connexion for additional downloading when we try to install them.

    3- If there is no way to avoid any additional internet downloading to complete the installation, how may we deal with the combination of these files with Windows XP with the help of nLite ?

    Will I be able to combine correctly these files with XP with the help of nLite, and when I will install my complete XP from what I will have obtained from nLite, will XP reclaim an internet connexion in order to download additional files to complete the installation of some .NET Framework ?


    I think that these questions may be of some interest for all those who would like to keep their XP operating system, because it may happen that Microsoft will cease to supply all the .NET Framework files for downloading in a relative near future.

    Could Ghacks write an article on that subject if you find it worth to do so ?

    I am a french speaking guy so if some of the things I said does not appear to be clear, do not hesitate to ask me questions so to clarify what is not clear…
