VS2012:清单创作错误c1010005:根元素名称应为<assembly/>

我从Microsoft文档中获取了清单文件: http://msdn.microsoft.com/en-us/library/ms742884.aspx 它不起作用!

<trustInfo xmlns="urn:0073chemas-microsoft-com:asm.v3">
    <security>
        <requestedPrivileges>
        <requestedExecutionLevel
            level="highestAvailable"
            UIAccess="true" />
        </requestedPrivileges>
    </security>
</trustInfo>
