让一个WebRole支持多个站点

在参考Configure a Web Role for Multiple Web Sites和Tips for Publishing Multiple Sites in a Web Role两篇文章后，用记事本打开Azure项目文件（*.ccproj），在尾部添加如下配置，即可实现多个站点共享一个WebRole，从而更有效的利用Azure资源。

<PropertyGroup>
    <!-- Inject the publication of "secondary" sites into the Windows Azure build/project packaging process. -->
    <CoreBuildDependsOn>
    CleanSecondarySites;
    PublishSecondarySites;
    $(CoreBuildDependsOn)
  </CoreBuildDependsOn>
    <!-- This is the directory within the web application project directory to which the project will be "published" for later packaging by the Azure project. -->
    <SecondarySitePublishDir>azure.publish\</SecondarySitePublishDir>
  </PropertyGroup>
  <!-- These SecondarySite items represent the collection of sites (other than the web application associated with the role) that need special packaging. -->
  <ItemGroup>
    <SecondarySite Include="..\Admin\Admin.csproj" />
    <SecondarySite Include="..\WebSite\WebSite.csproj" />
  </ItemGroup>
  <Target Name="CleanSecondarySites">
    <RemoveDir Directories="%(SecondarySite.RootDir)%(Directory)$(SecondarySitePublishDir)" />
  </Target>
  <Target Name="PublishSecondarySites" Condition="'$(PackageForComputeEmulator)' == 'true'&#xD;&#xA;                      Or '$(IsExecutingPublishTarget)' == 'true' ">
    <!--
    Execute the Build (and more importantly the _WPPCopyWebApplication) target to "publish" each secondary web application project.
     
    Note the setting of the WebProjectOutputDir property; this is where the project will be published to be later picked up by CSPack.
  -->
    <MSBuild Projects="%(SecondarySite.Identity)" Targets="Build;_WPPCopyWebApplication" Properties="Configuration=$(Configuration);Platform=$(Platform);WebProjectOutputDir=$(SecondarySitePublishDir)" />
  </Target>
