System.Diagnostics.Trace in referenced Class Library project

Question

I have a Asp.Net (Web Api) project. In this project I reference another Class Library project.

The traces that are written in the referenced Class Library don't show up in my Log.

How can I make the traces off both projects show up in the same Log using System.Diagnostics ? In other words, how can I make the referenced Class Library use the web.config Diagnostics settings from the Api Project? And if this isn't possible, how can I get the Traces that are written in the referenced Class Library in a Log at all?

I tried to add the System.Diagnostics settings from the web.config to a app.config but this doesn't seem to do anything at all.

Api project:

TraceSource source = new TraceSource("MyProject");
source.TraceEvent(TraceEventType.Information, 1, "My logged Trace");

Referenced class library:

TraceSource source = new TraceSource("MyProject");
source.TraceEvent(TraceEventType.Information, 1, "My disappearing Trace");

Web.config

<system.diagnostics>
  <sources>
    <source name="MyProject" switchValue="All">
      <listeners>
        <clear />
        <add name="log" />
      </listeners>
    </source>
  </sources>
  <sharedListeners>
    <add name="log"
         type="System.Diagnostics.XmlWriterTraceListener"
         initializeData="Log.svclog"
    />
  </sharedListeners>
  <trace autoflush="true"/>
</system.diagnostics>

You need to configure trace listeners according to your class library configuration of tracesources. Do you own the code ?
