检查登记用于IIS ScriptMaps中的.svc扩展。要做到这一点，您可以使用WIX自定义操作中的WMI，这些操作以Javascript，VBScript或C/C++实现。这里是一个例子在Javascript中：

// IsWcf.js 
// ------------------------------------------------------------------ 
// 
// detect if WCF is installed; suitable for use within a WIX Custom Action. 
// 
// Copyright 2010, Cheeso. 
// 
// Licensed under the MS Public License 
// http://opensource.org/licenses/ms-pl.html 
// 
// To use this as a Custom Action in a WIX project, register it this way: 
// 
// <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> 
//  <Fragment> 
//  <Binary Id="B.JavaScript" SourceFile="CustomActions.js" /> 
//  <CustomAction Id="CA.DetectWcf" 
//      BinaryKey="B.JavaScript" 
//      JScriptCall="DetectWcf_CA" 
//      Execute="immediate" 
//      Return="check" /> 
//  </Fragment> 
// </Wix> 
// 
// And invoke it this way: 
// 
// <InstallUISequence> 
//  <Custom Action="CA.DetectWcf" After="CostFinalize" Overridable="yes">NOT Installed</Custom> 
// </InstallUISequence> 
// 
//
