Setting web.config properties during build (not through publishing)

I'm trying to deploy an app using a Web Setup Proj开发者_Go百科ect. The problem I'm running into is that the web.config file is never transformed. According to this post it's by design that transformation only takes place during a publish. How do I get the web.config properties to update correctly if building the Setup Project in turn calls the other assemblies build command?

I fixed it by adding a dummy web.Template.config file like Andriy K suggested in this post, and then calling TransformXml during my BeforeBuild event like so:

<Target Name="BeforeBuild">
<TransformXml Source="$(WebFolderName)Web.Template.config"
              Transform="$(WebFolderName)Web.$(Configuration).config"
              Destination="$(WebFolderName)Web.config" />
</Target>

The simplest option is to install a command-line xslt utility and launch it in the post-build action of your project. You could also use one of the many MSBuild XSLT tasks and add it into the .csproj file. (It's just an MSBuild script file; there are comments already in there near the bottom explaining how to customize the build.)

You could also perform either of these steps in the pre-build action of your setup project, instead of the post-build action of your web application. If you also use the publishing wizard, this second option may work better as it won't interfere with the normal XSLT transforming going on in the publisher.
