System.Diagnostics.Tracing Build Errors in Mono
<p>I'm trying to build a project in Mono (v4.4.1) that makes use of the System.Diagnostics.Tracing dll but I continually run into build errors:</p>

<pre><code>/usr/lib/mono/4.5/Microsoft.CSharp.targets (CoreCompile target) -&gt;

Context/TplFrameworkListenerBase.cs(12,54): error CS0246: The type or namespace name `EventListener' could not be found. Are you missing an assembly reference?
Context/TplFrameworkListenerBase.cs(52,40): error CS0115: `FastTrack.Context.TplFrameworkListenerBase.OnEventSourceCreated(System.Diagnostics.Tracing.EventSource)' is marked as an override but no suitable method found to override
Context/TplFrameworkListenerBase.cs(114,55): error CS0246: The type or namespace name `EventWrittenEventArgs' could not be found. Are you missing an assembly reference?
Context/TplFrameworkListenerBase.cs(142,31): error CS0246: The type or namespace name `EventWrittenEventArgs' could not be found. Are you missing an assembly reference?
Context/TplFrameworkListenerBase.cs(147,69): error CS0246: The type or namespace name `EventWrittenEventArgs' could not be found. Are you missing an assembly reference?
</code></pre>

<p>I've tried also adding the nuget package as well as manually adding a reference to System.Diagnostics.Tracing.dll and including the dll in the repo. When I manually add the reference it says I have two of the same references included in the project and won't build. Is there a way to get this working or are these properties just not implemented in the newest version of mono?</p>
