I'm developing a windows phone application on Visual Studio 2010, Windows 8 x86. I've setup Visual Studio to Run as an administrator. Every time I try to run the windows phone 7 application, i have also updated sdk 7.1.1 but it still gives me this error:

Windows Phone: Deployment of application to device failed. Exception from HRESULT: 0x89721800

is there any solution regarding this?

Start from here! And you understand all.

for wp7.1 

System requirements
Supported operating systems: Windows 7, Windows Vista

Windows® Vista® (x86 and x64) with Service Pack 2 – all editions except Starter Edition
Windows 7 (x86 and x64) – all editions except Starter Edition
Installation requires 4 GB of free disk space on the system drive.
3 GB RAM
Windows Phone Emulator requires a DirectX 10 or above capable graphics card with a WDDM 1.1 driver

The Windows Phone SDK 7.1 is compatible with the final version of Visual Studio 2010 SP1.

for wp8

System requirements
Supported operating systems: Windows 8, Windows 8 Pro

Operating system type:
Windows 8 64-bit (x64) client versions
Hardware:
6.5 GB of free hard disk space
4 GB RAM
64-bit (x64) CPU
Windows Phone 8 Emulator:
Windows 8 Pro edition or greater
Requires a processor that supports Second Level Address Translation (SLAT)
If your computer meets the hardware and operating system requirements, but does not meet the requirements for the Windows Phone 8 Emulator, the Windows Phone SDK 8.0 will install and run. However, the Windows Phone 8 Emulator will not function and you will not be able to deploy or test apps on the Windows Phone 8 Emulator.

Basically, you need Win 8 64x or Win7.

Visual Studio 数据存储已损坏。

尝试：

  1. 关闭所有可能当前正在运行的 Visual Studio 实例。
  2. 删除文件夹“%LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon\10.0”</li>
  3. 启动 Visual Studio 的新实例
