If you are a Windows 7 DirectX developer who uses the June 2010 DirectX Software Development Kit (SDK), you'll have to update your development environments after you install this platform update. The following .dll files that are associated with this SDK are incompatible with this platform update:

• D3D10SDKLayers.dll
• D3D11SDKLayers.dll
• D3D10ref.dll
• D2D1debug.dll

You can use one of the following applications or tools to update these .dll files:

• The Windows 8 SDK: This SDK updates the current development environment with new headers, libs, and tools. These include the development .dll files from the preceding list. This update does not update the C or C++ compilers or the IDE, but it does let developers integrate the new features of the platform update into their applications.
• Microsoft Visual Studio 2012: This application includes the Windows 8 SDK, the Visual Studio 2012 IDE, and the new compilers. It also lets developers integrate the new features of the platform update into their applications.
• Remote Tools for Visual Studio 2012: These tools represent the minimum requirement in order to continue using the Direct3D debug layer. These tools update only the development .dll files from the preceding list. They do not enable developers to integrate the new features of the platform update into their applications. These tools are available in the "Remote Tools for Visual Studio 2012" section of the Visual Studio Download Center, or they can be downloaded from the following links:
  • Remote Tools for Visual Studio 2012 (x86) English
  • Remote Tools for Visual Studio 2012 (x64) English
  
  Note The Pix for Windows tool from the DirectX SDK is incompatible with this platform update. See Debugging Shaders in Visual Studio for more information about the new tools that are available in Visual Studio 2012.
