在尝试使用Powershell提供的简单WCF服务（Hello world）时，出现了一些小问题

这是我有史以来第一次尝试从Powershell使用一个简单的WCF服务，结果遇到了麻烦

我指的是设置环境变量的链接，如下所示

$env:VSINSTALLDIR="$env:Program Files\Microsoft Visual Studio 10.0"
$env:VCINSTALLDIR="$env:Program Files\Microsoft Visual Studio 10.0\VC"
$env:DevEnvDir="$env:VSINSTALLDIR\Common7\IDE"
$env:FrameworkSDKDir="$env:VSINSTALLDIR\SDK\v3.5"
$FrameworkPath=$([System.Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory())
$env:FrameworkDir=$(split-path $FrameworkPath -Parent)
$env:FrameworkVersion=$(split-path $FrameworkPath -Leaf)
$env:PATH="$env:VSINSTALLDIR\Common7\IDE;$env:VCINSTALLDIR\BIN;$env:VSINSTALLDIR\Common7\Tools;$env:VSINSTALLDIR\Common7\Tools\bin;$env:VCINSTALLDIR\PlatformSDK\bin;$env:FrameworkSDKDir\bin;$env:FrameworkDir\$env:FrameworkVersion;$env:VCINSTALLDIR\VCPackages;$env:PATH"
$env:INCLUDE="$env:VCINSTALLDIR\ATLMFC\INCLUDE;$env:VCINSTALLDIR\INCLUDE;$env:VCINSTALLDIR\PlatformSDK\include;$env:FrameworkSDKDir\include;$env:INCLUDE"
$env:LIB="$env:VCINSTALLDIR\ATLMFC\LIB;$env:VCINSTALLDIR\LIB;$env:VCINSTALLDIR\PlatformSDK\lib;$env:FrameworkSDKDir\lib;$env:LIB"
$env:LIBPATH="$FrameworkPath;$env:VCINSTALLDIR\ATLMFC\LIB"

上面提到的链接是针对VS2005的，但我使用的是VS2010。此后，一些参数值将根据我的设置进行更改

然后，当我试图从PowerShell命令提示符下通过发出

wsdl.exe http://localhost:55853/Service1.svc?wsdl

我遇到了一个错误

术语“wsdl.exe”不能识别为cmdlet、函数、脚本文件或可操作程序的名称。检查sp 输入名称，或者如果包含路径，请验证路径是否正确，然后重试。 第1行字符：9

+wsdl.exe您的Program Files环境变量的名称错误，此代码应该可以工作：

$env:VSINSTALLDIR="$env:ProgramFiles\Microsoft Visual Studio 10.0"
$env:VCINSTALLDIR="$env:ProgramFiles\Microsoft Visual Studio 10.0\VC"
$env:DevEnvDir="$env:VSINSTALLDIR\Common7\IDE"
$env:FrameworkSDKDir="$env:VSINSTALLDIR\SDK\v3.5"
$FrameworkPath=$([System.Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory())
$env:FrameworkDir=$(split-path $FrameworkPath -Parent)
$env:FrameworkVersion=$(split-path $FrameworkPath -Leaf)
$env:PATH="$env:VSINSTALLDIR\Common7\IDE;$env:VCINSTALLDIR\BIN;$env:VSINSTALLDIR\Common7\Tools;$env:VSINSTALLDIR\Common7\Tools\bin;$env:VCINSTALLDIR\PlatformSDK\bin;$env:FrameworkSDKDir\bin;$env:FrameworkDir\$env:FrameworkVersion;$env:VCINSTALLDIR\VCPackages;$env:PATH"
$env:INCLUDE="$env:VCINSTALLDIR\ATLMFC\INCLUDE;$env:VCINSTALLDIR\INCLUDE;$env:VCINSTALLDIR\PlatformSDK\include;$env:FrameworkSDKDir\include;$env:INCLUDE"
$env:LIB="$env:VCINSTALLDIR\ATLMFC\LIB;$env:VCINSTALLDIR\LIB;$env:VCINSTALLDIR\PlatformSDK\lib;$env:FrameworkSDKDir\lib;$env:LIB"
$env:LIBPATH="$FrameworkPath;$env:VCINSTALLDIR\ATLMFC\LIB"

为什么是powershell v1而不是v2？
