Cake -Experimental Switch Compile Error
<p>I am trying to use the Cake-Plist addin and received an error that dynamic is not yet implemented in the version of Roslyn that was being used.  Then from advise for someone else I was told to try the -Experimental switch.  When using the switch I am receiving the following error when it is trying to compile the build script.</p>

<pre><code>Error: Microsoft.CodeAnalysis.Scripting.CompilationErrorException: (2,1): error CS0656: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create'

<p>Does anyone know what is causing this error?</p>
