Take backup of target dir before files are copied

问题:

I am using a regular Visual Studio Setup Project to deploy my ASP.NET application. I need to handle the case of an existing web.config existing in the target directory. When one is found, it needs to be renamed before the install takes place. If this does not happen, the new web.config will not overwrite the old. How can I get my custom action to rename the old web.config BEFORE the files being installed are copied? So far I have tried by deriving from System.Configuration.Install.Installer and overriding the OnBeforeInstall, Install and Commit. It seems that all of these methods take place after the new files are copied into the target directory.

I found solution my self.!

you have to edit WebDeploy project Right click and OpenProject File. and its Extension must be .wdproj.

Add these Property Group

<PropertyGroup>
<TransformWebConfigEnabled>False</TransformWebConfigEnabled>    <AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
  </PropertyGroup>
