   Compatibility Issue
  From www.microsoft.com:What's New in the March 2008 DirectX SDKChanges in Visual Studio SupportThe March 2008 DirectX SDK includes support for Visual Studio 2008. The DirectX SDK continues to maintain support for Visual Studio 2005, but Visual Studio 2003 is no longer supported.I have the August 2007 DirectX SDK, Microsoft Visual Studio 2008 Express Edition, Windows SDK, and it also works fine. What is meant by including support for Visual Studio 2008? I have compiled some of the sample applications from Samples folder in DirectX directory. All have compiled and worked fine. It seems to me, that the August 2007 DirectX SDK also supports Visual Studio 2008, but I may be wrong.Is there something that I'm not aware of? Because for me everything works fine as before (with Visual Studio 2005).   
  It may have worked before, but not officially. If anythign went wrong with the setup process or compiling or anything, Microsoft would have nothing to do with it. It's now officially supported though - if there's a problem caused by using the SDK with VC2008, it'll be fixed.   ;  Thanks for answering!So, it should work fine as far there are no errors or problems.   ;Quote:Original post by JPSThanks for answering!So, it should work fine as far there are no errors or problems.It should, but I'd still recommend updating to the latest SDK, since there's various improvements across the board. The only reason not to would be if you have a very slow Internet connection (Since the SDKs can be pretty huge...).   ;  Yeah, I have thought about updating, but since I'm still learning DirectX, and my resources sometimes use DirectX old components like DirectPlay and DirectMusic and so. So, at least now, I'd still like to use the August 2007 SDK (last SDK to have old components).By the way, do you know any good resources for learning latest SDK's except DirectX' own reference?
