How to: Transform Web.config When Deploying a Web Site Project

How to: Transform Web.config When Deploying a Web Site Project

Publishing a Web Site project with Visual Studio does not support Web.config transform files. In the following, I will show you how to use the same functionality from a Web Application project (see: How to: Transform Web.config When Deploying a Web Application Project) in a Web site project.

You have to create a publish profile for the Web Site project and add an MSBuild step in the "website.publishproj" file:

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  ...

  <Import Project="$(_WebPublishTargetsPath)\Web\Microsoft.WebSite.Publishing.targets" />

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Tasks.dll"/>

  <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

  <Target Name="BeforeBuild">

    <TransformXml Source="$(WebFolderName)Web.config"

                  Transform="$(WebFolderName)Web.$(Configuration).config"

                  Destination="$(WebFolderName)Web.config" />

  </Target>

  ...

</Project>
