Description Brett van Swelm 2012-11-16 13:00:22 UTC
Mono MCS requires "System.Xml.Linq" DLL reference when MS CSC doesn't. I'm not sure why there is this discrepancy as this doesn't seem an obvious requirement. Below is a reproducer, as minimal as I can make it:

With "D:\Applications\Mono-2.11.4\bin" and "C:\Windows\Microsoft.NET\Framework\v4.0.30319" in the path on my Windows 7 machine:

"/reference:C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Activities.dll"
"/reference:C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.dll"

SystemXmlLinq.cs
===== end =====

===== SystemXmlLinq.cs =====
using System;
using System.Activities;
using System.ServiceModel;
using System.ServiceModel.Activities;

public class SystemXmlLinq
{
    public static void Main(String[] args) {
        WorkflowControlEndpoint myEndPoint = new WorkflowControlEndpoint(
            new BasicHttpBinding(),
            new EndpointAddress(new Uri("")));

        WorkflowServiceHost host = new WorkflowServiceHost((Activity)null);
        host.AddServiceEndpoint(myEndPoint);
    }
}
===== end =====
