For additional information please see along with reviewing the Readme for last-minute updates. Users wishing to install the DirectX runtime for the purposes of playing a game should instead install the DirectX Websetup. See related resources at the bottom of this page. Visual Studio 2010 Support The June 2010 DirectX SDK includes support for Visual Studio 2010. The DirectX SDK will continue to support Visual Studio 2008 as well. However, Visual Studio 2005 will no longer be supported. PIX: Object Naming Support The June 2010 version of PIX supports naming for most resource objects in Direct3D D3D. Direct3D enables developers to attach arbitrary data to objects in D3D code using the SetPrivateData API for application-specific usage. PIX will now display specific string data for objects in the Object Table and other user interface elements where a human-readable object name will provide a much more effective experience for the user. XNAMath C++ SIMD Math Library The June 2010 release updates XNAMath to version 2. This change makes legacy data-type names equivalent to the new version-less data-type names. Therefore, you can use either legacy or version-less names. However, your code will be cleaner and easier to maintain if you use the version-less names. Therefore, you are no longer required to use D3d10. New HLSL Compiler fixes and features The HLSL Effects compiler fxc. Previous Releases For a description of what was added in previous releases, see Features Introduced in Previous Releases in the DirectX SDK documentation. Known Issues with the June 2010 DirectX SDK Support for Visual Studio 2010 and Visual Studio 2005 Beginning with the June 2010 release, the DirectX SDK supports Visual Studio 2010. The June 2010 release continues to support Visual Studio 2008 Service Pack 1. The DirectX SDK no longer supports Visual Studio 2005; the February 2010 release was the last release to support Visual Studio 2005. Support for DirectSetup Beginning with the June 2010 DirectX SDK, DirectSetup no longer supports operating systems earlier than Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1. Visual Studio 2008 Path Registration Sometimes Fails In the June 2010 release, the DirectX SDK installer will attempt to automatically register the executable, include, and library path settings needed for compilation of samples and other DirectX programs. In some circumstances, however, automatic registration fails and, therefore, attempts to include DirectX SDK headers result in errors. To work around this issue, manually add the proper path registration to Visual Studio. With Visual Studio 2010, paths are now specified on a per-project basis on a VC++ Directories page. New projects that make use of DirectX SDK headers, libraries, or tools should have these references added to the VC++ Directories property page. Samples Content Exporter Requires Visual Studio 2008 In the June 2010 DirectX SDK, the Samples Content Exporter is designed to use Autodesk FBX SDK 2010. The Samples Content Exporter does not work with later versions of the Autodesk FBX SDK 2011. Also, the Autodesk FBX SDK does not yet support Visual Studio 2010, and the DirectX SDK Visual Studio 2010 projects for the Samples Content Exporter therefore use the 'v90' toolset provided with Visual Studio 2008. As a result, you must have Visual Studio 2008 installed in order to compile the Samples Content Exporter. For more information, see the Visual Studio team blog post entry:. Help Integration for Visual Studio 2010 The new Microsoft Help System MHS , delivered via Visual Studio 2010, enables you to view documents on the MSDN Library using a standard browser. You can also select documents to download from the MSDN Online content publication web site MSDN cloud to your computer for viewing when a connection to the Internet is unavailable or undesirable. You can access this functionality from the Help Library Manager. To launch the Help Library Manager, select: Start All Programs Visual Studio 2010 Visual Studio Tools Help Library Manager The MHS is set to Online Mode by default. The first time you click a Help shortcut, you will be asked to confirm that you wish to connect to the Internet to view documentation in the MSDN cloud. If you wish to view documentation when a connection to the Internet is unavailable, you can import documentation sets books from the MSDN cloud and install these books to your computer. You can then switch to Offline Mode to view content on your computer by default. Documentation Organization Beginning with the August 2009 DirectX SDK, the Windows Graphics documentation is provided as a separate documentation collection from the main DirectX SDK documentation collection. The Windows graphics documentation collection includes content for Direct3D 9, Direct3D 10. Direct2D Documentation In the June 2010 release, the Direct2D documentation is incorrectly marked preliminary and subject to change. This is the official, release documentation for Direct2D; this warning can be safely ignored. Direct3D 11 Runtime To obtain the Direct3D 11 runtime, please install the release version of Windows 7 or Windows Server 2008 R2. Windows Vista users can follow the procedure described in or for corporate network users. For more details, see Direct3D 11 Deployment for Game Developers. Effects 11 The Effects runtime for Direct3D 11 FX11 is available as shared source in the DirectX SDK. For more information, please refer to Effects Direct3D 11 and Effect System Interfaces Direct3D 11 in the Windows Graphics documentation. DirectX 11 Runtime Symbols The modern DirectX Runtime is part of the operating system OS , and symbols for the DirectX components Direct3D, DirectInput, DirectSound, etc. DirectX 11 Runtime symbols are included in the Windows 7 and Windows Server 2008 R2 symbols packages available on the Microsoft website. However, we recommend using the Microsoft symbols server instead for the most current and correct set of symbols when debugging DirectX applications. Note that DirectX 11 Runtime symbols for the down-level and update for Windows Vista and Windows Server 2008 are not included in the OS offline symbols package. They can be obtained from the Microsoft symbol server. If you use this DLL on Windows XP SP3 with an application that uses the Windows Presentation Framework WPF , the code in the DLL will assert. This issue does not occur on Windows Vista or Windows 7. If you require only debug output, that is, you do not require symbols, you could also use the checked version of D3D9. Just rename the checked D3D9. The checked version of D3D9. Control Panel for DirectX 9 Debug Output is Specific to 32-bit or 64-bit Applications In order to turn DirectX 9 debug output on or off, you must use the DirectX control panel appropriate to the application being debugged. Use the 64-bit DirectX control panel for 64-bit applications and the x86 DirectX control panel for 32-bit applications. This change decouples the compiler from D3DX. New Warning X3206: Implicit Truncation of Vector Type Beginning in the August 2009 release of the DirectX SDK, the HLSL compiler will warn when an implicit truncation of a vector type occurs. For example, the follow code would elicit the warning. We recommend using the symbol server rather than using the included partial symbols package. For instructions about using the Microsoft Symbol Server, see. This SDK supports Visual Studio 2008 Service Pack 1 and Visual Studio 2010. To fix the issue, developers need to either reinstall the DirectX SDK or manually add the paths to Visual Studio 2008. On the Win32 platform, make sure that there is a reference to the DirectX headers. They may require you to disable virus protection software until SDK installation is completed. On the Start menu, right-click My Computer, and then click Manage. The Computer Management window appears. In the left navigation pane, click Services and Applications. In the right pane, double-click Services, and then double-click Cryptographic Services. The Cryptographic Services Properties property sheet appears. On the General tab, ensure that Service Status is Started, and that Startup Type is Automatic. This is by design, and should be enabled.
