Windows Phone Emulator

• Windows Phone Emulator requires a Microsoft DirectX® 10 or DirectX 11 graphics card with Windows Display Driver Model (WDDM) 1.1 driver and DDI 10 and later versions.
• Windows Phone Emulator requires GPU emulation to support certain scenarios such as profiling application performance, XNA® Framework applications, and displaying content in web browser controls.
• Windows Phone Emulator supports GPU peripheral emulation using the host GPU on computers that meet Windows Phone SDK 7.1.1 Update system requirements. On all other computers, the emulator reverts to software emulation, which is not supported.

Windows Phone SDK 7.1 must be installed on your computer before you can install Windows Phone SDK 7.1.1. For more information, see Installing Windows Phone SDK.

To install Windows Phone SDK 7.1.1 Update, click the Download button for WPSDK-7.1.1-KB2669191-x86.exe file, and then follow the instructions to install the SDK.

Note: This update configures a 256-MB emulator and a 512-MB emulator as part of the installation, and so might take longer to install than a typical SDK.
