.NET 4.0 and his Web.Config's XDT

Question

Hello, I'm trying to use the XDT in a 4.0 web application and I just don't figure out how! I know this is maybe weird (At least, all thread I've read since then, everybody seems to do it easly but hum, not me!!). Nothing working. Here's what I've tryed :

Here's my Web.Debug.Config :

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"&gt;

  <appSettings xdt:Transform="Replace">
    <add key="ConnectionString.SQL Server (SqlClient)"
     value="data source=test;initial catalog=TestDB;User ID=sa;Password=testpsw;persist security info=False;packet size=4096"  />
  </appSettings>

  <connectionStrings xdt:Transform="Replace">
    <add name="ASP.net Authentication"
     connectionString="data source=(local);initial catalog=TestDB;User ID=sa;Password=testpsw;persist security info=False" />
  </connectionStrings>

</configuration>

In my web.config, I've got this and plenty of other things but I just want to change those.

<?xml version="1.0"?>
[...]
<configuration>

  <appSettings>
    <add key="ConnectionString.SQL Server (SqlClient)"
     value="data source=[THIS WILL CHANGE];initial catalog=[THIS WILL CHANGE];User ID=[THIS WILL CHANGE];Password=[THIS WILL CHANGE];persist security info=False;packet size=4096"  />
  </appSettings>

  <connectionStrings>
    <add name="ASP.net Authentication"
     connectionString="data source=[THIS WILL CHANGE];initial catalog=[THIS WILL CHANGE];User ID=[THIS WILL CHANGE];Password=[THIS WILL CHANGE];persist security info=False" />
  </connectionStrings>

</configuration>
[...]

What I'm doing wrong?

Note : I've read the post from MSDN and it do not helped me...

To perform a web.config transformation on a web application, you have to deploy the project. Right click on the project and go to Publish.

Just building a project locally will not perform the transformation.
