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,

        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.

        I will Migrate my application to Java based. It is not that we should worry about it my all future projects will be built in JAVA if this is the case with MS.

        Hi our application right now deployed in Windows server 2003 R2 Trager framework 2.0. we can upgrade target frame work to .net Frame work 4.5.1?

        It works on XP with Mono. Maybe I'll just use Mono. Why do I need SM again?

        I started using .Net 4.5. I was very excited. I was going to use all of these new features. Then I realized it doesn't work on XP. Sad trombone... I will not be using .Net 4.5 now. Unless you can magically make all of my customer's computers run Win7?

        We want .Net 4.5 to work on XP! WAH......................

        Based on votes, this request is currently No.10 on ALL request categories.

        What we get from Visual Studio Team: DECLINED and a generic reply that has nothing to do with the request.

        For my next project I will target these platforms:

        Windows: DECLINED
        Windows Phone: DECLINED
        iOS: ACCEPTED
        Android: ACCEPTED
        MAC OS: ACCEPTED

        At least support .NET 4.5 on Windows 2003 R2 & SP2 - it is not at end of life yet for corporate level support

      • softboy99softboy99 commented  ·   ·  Flag as inappropriate

        The CEO changed,we wish MS can regains its engineer culture. Get closer to the developer voice. This voice is second voted of the whole site.We really wish MS reconsider its strategy of .net around windows. Still that world,MS should popularize its new version OS by the OS itself not by other peripheral tools. Lost the developers will lost the whole ECO and finally lost windows and office too not only the mobile area. It is merely a matter of time.

        Since .NET is supposed to run on any Microsoft WIndows platform at least, it should be supported on all Windows OS at least above XP SP3 and higher.
