using WatiN.Core出错

[看似疯癫]

代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using WatiN.Core;

using System.Threading;


namespace WatiNTest
{
class Program
{
[STAThread]
static void Main(string[] args)
{
// Open a new Internet Explorer window and
// goto the google website.
IE ie = new IE("http://www.google.com.hk", true);

// Find the search text field and type Watin in it.
ie.TextField(Find.ByName("q")).TypeText("WatiN");

// Click the Google search button.
ie.Button(Find.ByValue("Google 搜索")).Click();

// Uncomment the following line if you want to close
// Internet Explorer and the console window immediately.
//ie.Close();

}
}
}
已经引入WatiN.Core.dll
如图，求解

看看你引用的System.Web 是不是4.0.0.0的
