做新项目，当时参考NopCommerce的结构，后台Nop.Admin是一个独立的Area Web Site，但部署的时候发现，使用一键发布，Admin Area会丢失。
研究了下NopCommerce的做法，使用MSBuild组织文件结构，关键的地方在下面：
<!--Now lets publish Nop.Admin-->
<MSBuild Projects="$(RootFolder)PresentationNop.WebAdministrationNop.Admin.csproj"
Targets="ResolveReferences;_CopyWebApplication"
Properties="WebProjectOutputDir=$(DeployFolder)$(DeployPrefix)Administration;
OutDir=$(DeployFolder)$(DeployPrefix)Administrationin;Configuration=$(Configuration)" />
<!--Now lets move the Nop.Admin/bin/ to the root bin/-->
<CreateItem Include="$(DeployFolder)$(DeployPrefix)Administrationin*.dll">
<Output TaskParameter="Include" ItemName="CompileOutput" />
</CreateItem>
<Copy SourceFiles="@(CompileOutput)"
DestinationFolder="$(DeployFolder)$(DeployPrefix)in" />
<!--Lets delete the bin in Nop.Admin-->
<RemoveDir Directories="$(DeployFolder)$(DeployPrefix)Administrationin" />
<!--Lets delete the packages.config files-->
<Delete Files="$(DeployFolder)$(DeployPrefix)Administrationpackages.config;
$(DeployFolder)$(DeployPrefix)packages.config"/>
然后发布的时候可以使用Web.Release.config替换Web.config
<!--Transform support-->
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)MicrosoftVisualStudiov$(VisualStudioVersion)WebMicrosoft.Web.Publishing.Tasks.dll"/>
<!--Transform root web.config file-->
<TransformXml Condition="Exists('$(WebFolder)Web.$(Configuration).config')" Source="$(WebFolder)Web.config" Transform="$(WebFolder)Web.$(Configuration).config" Destination="$(DeployFolder)$(DeployPrefix)Web.config" />
使用Settings.Release.txt替换Settings.txt
<!--Lets Copy App_DataSettings.Release.txt To App_DataSettings.txt -->
<Copy Condition="Exists('$(WebFolder)App_DataSettings.$(Configuration).txt')"
SourceFiles="$(WebFolder)App_DataSettings.$(Configuration).txt"
DestinationFiles="$(DeployFolder)$(DeployPrefix)App_DataSettings.txt"
SkipUnchangedFiles="true" OverwriteReadOnlyFiles="true" />
<!--Lets delete the Settings.Release.txt file-->
<Delete Condition="Exists('$(DeployFolder)$(DeployPrefix)App_DataSettings.$(Configuration).txt')"
Files="$(DeployFolder)$(DeployPrefix)App_DataSettings.$(Configuration).txt"/>
MSBuild配置文件，可下载参考。
装了Win8+VS2013后，生成时会提示：
error MSB4019: 未找到导入的项目“C:Program Files (x86)MSBuildMicrosoftVisualStudiov11.0WebApplicationsMicrosoft.WebApplication.targets”。请确认 <Import> 声明中的路径正确，且磁盘上存在该文件。
解决方法：
在命令行使用"C:Program Files (x86)MSBuild12.0BinMSBuild.exe"替换”%windir%Microsoft.NETFrameworkv4.0.30319MSBuild.exe“
或者从别的开发机上复制一份WebApplications
