I'm using mono from svn... I'm trying to use the SharpSSH library but it failed
with some : System.Threading.SynchronizationLockException: Object is not
synchronized


After more investigation i've find this problem :

this program :
using System;
using System.Threading;
using System.Runtime.CompilerServices;

namespace TestLocks
{
        class MainClass
        {
                public static void Main(string[] args)
                {
                        MainClass MainClassInstance=new MainClass();
                        MainClassInstance.LockMethod();
                }

                [MethodImpl(MethodImplOptions.Synchronized)]
                public virtual void LockMethod()
                {
                        Monitor.PulseAll(this);
                        Console.WriteLine("Hello World!");
                }
        }
}

don't work and fails with Unhandled Exception:
System.Threading.SynchronizationLockException: Object is not synchronized

and this program :
using System;
using System.Threading;
using System.Runtime.CompilerServices;

namespace TestLocks
{
        class MainClass
        {
                public static void Main(string[] args)
                {
                        MainClass MainClassInstance=new MainClass();
                        MainClassInstance.LockMethod();
                }

                [MethodImpl(MethodImplOptions.Synchronized)]
                public void LockMethod()
                {
                        Monitor.PulseAll(this);
                        Console.WriteLine("Hello World!");
                }
        }
}

work well...

It seems there's a problem with [MethodImpl(MethodImplOptions.Synchronized)] on
virtual method...
