I suggest you ...

Make .NET 4.5 work on any OS that supports 4.0

.NET Framework 4.0: Supported operating systems: Windows 7, Windows Server 2008 R2, Windows Vista Service Pack 1, Windows Server 2008, Windows XP Service Pack 3, Windows Server 2003 Service Pack 2

.NET Framework 4.5 Beta: Supported operating systems: Windows 8, Windows Server 8, Windows 7, Windows Server 2008 R2, Windows Server 2008

If 4.5 is an in-place upgrade, it should support every OS that supports 4.0; wait until 5.0 to drop support for Vista and XP.

Thanks to everyone for sharing your feedback on this issue. VS 2012 supported platforms are now published here (http://www.microsoft.com/visualstudio/11/en-us/products/compatibility ). While Windows XP and Windows Server 2003 are not supported for .NET Framework 4.5, they remain as supported targeted platforms in VS 2012. More information is available here (http://blogs.msdn.com/b/visualstudio/archive/2012/05/18/a-look-ahead-at-the-visual-studio-11-product-lineup-and-platform-support.aspx)

Thank you,

    Make .net 4.5 and higher versions available on Windows XP. Still the OS is using widely. It's preventing us to developing in 4.5.

    So much for .NET's "write in any language, deploy anywhere". Walk me through this, Microsoft. With Roslyn, you can deploy to Ubuntu, but not to XP? Why are Microsoft products no longer under your support worse than Linux which was never under your support in the first place??

    We need .net 4.5 on Xp. The issues for us are many:

    #1. Every MS update requires a complete relearning of the system. Updates, hardware, drivers, patches, and then learn where everything is and how to make all your aps work again.

    #2. Every MS update then requires a few to several months for all the bugs to get fixed and they issue the patch/update, etc. Meanwhile we are the guinea pigs. For home users that may be fine if they choose to put up with it. But for business users, it's impossible.

    #3. Xp really was the last great OS MS put out. Everything after that has been trying to copy Apple. If we wanted an Apple looking OS would buy Apple.

    With that said, MS should sell the rights to Xp to someone who can develop for the 25-30% of computers still out there using it.

    .net now is moving to Linux,Mac OS, but have left its own windows XP. Its so funny. Dose Satya Nadella know about this?

    We want .Net 4.5 for NT 4.0!
    We want .Net 4.5 for Windows 95!
    We want .Net 4.5 for Ubuntu!
    We want .Net 4.5 for Android!
    And I am absolutely dissatisfied with Cadillac, they are not developing hybrid engine for my '69 Eldorado!

    now, .net is open sourcing and cross platform,of course,just .net core. so, why abandon XP. abandon xp is not a technical issue, it is just a MS business issue. Please everyone come here to vote more and more votes and make the MS management to know the voice.

    Please, keep xp updated with 5.0 either, there are so many people like me out there that are still using this wonderful OS.

    Microsoft's actions to artificially cripple Windog XP reveals a boneheaded and desperate company, whose main goal is to squeeze users by forcing them to port into Windog 7 is despicable.

    As I said many times in the past, Microsoft has become purely irrelevant as a software manufacturer.

    I actually support Microsoft on this one. One of my clients is running 2003 on the public farm and so I can't use 4.5, but these OSes are really quite old. The elephant in the room here is that my client needs to upgrade pretty darn quickly or move to Azure.

    This is a worrying step, it seems we will have issues in the future of what is not supported by MS development platforms. Win XP and server 2003 should be supported by .Net 4.5 and later frameworks Because they are being used by many clients.
