How to transform log4net config like web.config?

Question

From my .csproj file:

<Content Include="log4net.config">
  <SubType>Designer</SubType>
</Content>
<Content Include="log4net.Release.config">
  <DependentUpon>log4net.config</DependentUpon>
</Content>
<Content Include="log4net.Debug.config">
  <DependentUpon>log4net.config</DependentUpon>
</Content>
<Content Include="log4net.Live.config">
  <DependentUpon>log4net.config</DependentUpon>   
</Content>
<Content Include="log4net.Demo.config">
  <DependentUpon>log4net.config</DependentUpon>   
</Content>  

At the bottom of my .csproj file:

  <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
  <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" />
    <Target Name="AfterCompile" Condition="exists('log4net.$(Configuration).config')">
      <TransformXml Source="log4net.config"
        Destination="$(IntermediateOutputPath)$(TargetFileName).config"
        Transform="log4net.$(Configuration).config" />
      <ItemGroup>
        <AppConfigWithTargetPath Remove="log4net.config"/>
        <AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
          <TargetPath>$(TargetFileName).config</TargetPath>
        </AppConfigWithTargetPath>
      </ItemGroup>
    </Target>

From log4net.config

<connectionString name="ConnName" 
value="Data Source=localhost\sqlexpress;Initial Catalog=localdb;Persist Security Info=True;Integrated Security=SSPI;" />

From log4net.Live.config (removed sensitive data)

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <connectionString name="ConnName" value="Data Source=127.0.0.1;Initial Catalog=DBName;Persist Security Info=True;User ID=userid;Password=pword"
        providerName="System.Data.SqlClient" xdt:Transform="Replace" xdt:Locator="Match(name)" />
</configuration>

I checked msbuild output and I see that it transformed my web.config correctly, but I see no output for it transforming log4net. Also, when I check the log4net.config file after publish, it has the original connection string.

What am I doing wrong :)?

Thanks!

Update

I had some errors in the code that msbuild were outputting as warnings that I didn't see. I fixed those and now I get some output from MSBuild:

AfterCompile: Transforming Source File: log4net.config Applying Transform File: log4net.Live.config Output File: obj\Live\Common.UI.Web.dll.config
Transformation succeeded

This is still a problem, because the file should be named log4net.config, not Common.UI.Web.dll.config...

For whatever reason

$(TargetFileName)

is taking on the name of the .csproj file name. If I replace it with just log4net, then it outputs correctly

Update

File is stuck in obj folder and is not getting picked up when publishing.

Ended up using http://mint.litemedia.se/2010/01/29/transforming-an-app-config-file/ for both the app config and the log4net config. Works very nicely.

For the log4net config, add this to the csproj:

<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
   <Target Name="ApplyConfiguration" Condition="Exists('log4net.$(Configuration).config')">  
       <XslTransformation XmlInputPaths="log4net.config" XslInputPath="log4net.$(Configuration).config" OutputPaths="log4net.config_output" />  
       <Copy SourceFiles="log4net.config_output" DestinationFiles="log4net.config" />  
   </Target>  
   <Target Name="BeforeBuild">  
       <CallTarget Targets="ApplyConfiguration"/>  
   </Target>
