What do these Visual Studio warnings mean?

Question

My Web.Config broadcasts are not published - and I think the error is related to these warnings that I receive.

Using Visual Studio 2010, I play with my file Web.Config/ Web.Config.Debug.

In my file, .DebugI get the following warning, indicated many times.

No element in the source document matches '/configuration'

I think it lists it for each section that exists in the file .Debug.

So, with the following sample Web.Config.Debug file, which will be listed twice. (I guess the first for <connectionStrings>..</>, and the second for <system.webServer>...</.>)

<?xml version="1.0"?>

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform" xdt:SupressWarnings="false">

    <connectionStrings>
        <add name="Foo" connectionString="Server=foo;Database=Foo;uid=foo;password=foo" providerName="System.Data.SqlClient"
            xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
    </connectionStrings>

    <system.webServer>
        <httpProtocol>
            <customHeaders>
                <clear />
                <add name="ETag" value="Dev_IIS" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />
            </customHeaders>
        </httpProtocol>
    </system.webServer>

</configuration>

Can anyone help please?
