创建Merge Modules
创建Merge Module与创建Windows Installer package非常相似。让我们先创建一个名为"module.wxs"的文本文件。如下输入标准的框架：
<?xml version='1.0'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'>
</Wix>

然后创建Merge Module，我们添加<Module/>元素以及所需的属性：

<?xml version='1.0'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'>
   <Module Id='TestModule' Guid='87654321-4321-4321-4321-210987654321' Language='1033' Version='1.0.0.0'>
      <Package Id='87654321-4321-4321-4321-210987654321' Description='My first Merge Module'
                Comments='This is my first attempt at creating a Windows Installer Merge Module'
                Manufacturer='Microsoft Corporation' InstallerVersion='200' Compressed='yes' />

   </Module>
</Wix>

编译和链接这个代码。你将得到一个非常小的.msm文件。让我象前面给Windows Installer package添加代码一样，给Merge Module添加一个文本文件。首先创建一个名为"readme2.txt"的文本文件，并输入一些不同的文字。然后，更新源码来包含这个文件：

<?xml version='1.0'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'>
   <Module Id='TestModule' Guid='87654321-4321-4321-4321-210987654321' Language='1033' Version='1.0.0.0'>
      <Package Id='87654321-4321-4321-4321-210987654321' Description='My first Merge Module'
                Comments='This is my first attempt at creating a Windows Installer Merge Module'
                Manufacturer='Microsoft Corporation' InstallerVersion='200' Compressed='yes' />
 
      <Directory Id='TARGETDIR' Name='SourceDir'>
         <Directory Id='MyModuleDirectory' Name='.'>
            <Component Id='MyModuleComponent' Guid='87654321-4321-4321-4321-110987654321'>
               <File Id='readme2' Name='readme2.txt' src='readme2.txt' />
            </Component>
         </Directory>
      </Directory>
   </Module>
</Wix>

现在，你有了一个Merge Module，它可以和其他团队共享来安装你的"readme2.txt"文件。让我们在Windows Installer package实际应用它。

将Merge Module合成到一个 .wxs 文件

Merge Modules只能合并到Windows Installer package。幸运的是，我们有了一个.wxs 文件用来创建Windows Installer package。因此让我们添加2行代码（是的，只有2行）来合并你的新模块。打开"product.wxs"，添加：

<?xml version='1.0'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'>
   <Product Id='12345678-1234-1234-1234-123456789012' Name='Test Package' Language='1033'
             Version='1.0.0.0' Manufacturer='Microsoft Corporation'>
      <Package Id='12345678-1234-1234-1234-123456789012' Description='My first Windows Installer package'
               Comments='This is my first attempt at creating a Windows Installer database'
               Manufacturer='Microsoft Corporation' InstallerVersion='200' Compressed='yes' />
 
      <Media Id='1' Cabinet='product.cab' EmbedCab='yes' />
 
      <Directory Id='TARGETDIR' Name='SourceDir'>
         <Directory Id='ProgramFilesFolder' Name='PFiles'>
            <Directory Id='MyDir' Name='Test Program'>
               <Component Id='MyComponent' Guid='12345678-1234-1234-1234-123456789012'>
                  <File Id='readme' Name='readme.txt' DiskId='1' src='readme.txt' />
               </Component>
 
               <Merge Id='MyModule' Language='1033' src='module.msm' DiskId='1' />
            </Directory>
         </Directory>
      </Directory>
 
      <Feature Id='MyFeature' Title='My 1st Feature' Level='1'>
         <ComponentRef Id='MyComponent' />
         <MergeRef Id='MyModule' />
      </Feature>
   </Product>
</Wix>

现在当你编译"product.wxs"，它将包含来自Merge Module的安装逻辑和文件。当你再次安装"product.msi"时，你应该在"Test Program"目录下看到两个文本文件。
