如何为委托参数提供XML注释/文档?

给一个代表

Func<string,string,string> MyFunc = (firstName,lastName) => string.Format("Given Name:{0} Surname:{1}",
                                                                            firstName,
                                                                            lastName);

您如何记录firstname和lastname的参数,以便它们以intellisense的形式显示(比如方法描述和参数)?
例子:

/// <summary>
/// My Method
/// </summary>
/// <param name="firstName">The first name.</param>
/// <param name="lastName">The last name.</param>
/// <returns></returns> 
public string MyMethod(string firstName, string lastName)
{ 
  return string.Format("Given Name:{0} Surname:{1}",firstName,lastName);
}

当我键入并告诉我委托参数的描述时,我希望将鼠标悬停在委托上或弹出IntelliSense,就像上面的方法一样。
