[nant-dev] Error creating custom task in a script tag

[Samuel Neff]

I have this code in my build file which should create a politer XmlPeek task:

<script language="c#">
    <code>
        <![CDATA[
            [TaskName("quietxmlpeek")]
            public class QuietXmlPeekTask : NAnt.Core.Tasks.XmlPeekTask {
                public override void Log(Level messageLevel, string message) {
                    if (messageLevel != Level.Info || Verbose) {
                        base.Log(messageLevel, message);
                    }
                }
            }
        ]]>
    </code>
</script>


But instead it generates this error:


   [script] Scanning assembly "y0viaire" for extensions.
   [script] Failure scanning "nant7028cc7dc1a14572b6c220cec1bbaae9+QuietXmlPeekTask, y0viaire, Version=0.0.0.0 , Culture=neutral, PublicKeyToken=null" for tasks.
