"One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?"的解决方法

#事故现场：

　　在一个.net 4.0 的项目中使用dynamic，示例代码如下：

1 private static void Main(string[] args)
2 {
3     dynamic obj;
4     obj = new { name = "jack" };
5     Console.WriteLine(obj.name);
6 }

　　在读取obj.name时，报错：

One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?

#解决方法：

　　在项目中，添加Microsoft.CSharp.dll的引用；
