尝试编译调用本机代码的类时,Mono编译器崩溃

Question

我有以下类使用Mono(在mac中)将一些运行循环调用从本机代码映射到C#,并且编译器不起作用,它在尝试编译时一直崩溃.我已将其删除到仅包含此类的单独项目,但它仍然已损坏,因此看起来问题是具体使用此代码.

有没有人见过这样的东西？

using System;
using System.Threading;

namespace Integration.Mac
{

    public class CommonRunLoop
    {

        static IntPtr runLoopReference;

        public static IntPtr CommonRunLoopReference {
            get {
                return runLoopReference;
            }
        }

        static CommonRunLoop() {

            AutoResetEvent lockObj = new AutoResetEvent (true);

            Thread runLoop = new Thread (delegate() {
                runLoopReference = CFRunLoopGetCurrent ();
                lockObj.Set ();
                CFRunLoopRun ();
            });

            runLoop.IsBackground = true;
            runLoop.Name = "Common-Sync-Run-Loop";
            lockObj.WaitOne();
        }

        [DllImport ("/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation")]
        extern static IntPtr CFRunLoopGetCurrent ();

        [DllImport ("/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation")]
        extern static IntPtr CFRunLoopGetMain ();

        [DllImport ("/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation")]
        extern static void CFRunLoopRun ();

    } 
}

编译器输出如下:

添加:

using System.Runtime.InteropServices;

在文件的开头修复它,DLLImport就在那个命名空间.不知道为什么编译器不只是抱怨它而不是崩溃.

这里填写了一份错误报告.
