为什么具有默认值枚举参数的泛型类的构造函数不能调用该类的受保护方法？

Question

A simple test case:

using System;

public class Test<T>
{
    public enum TestEnum
    {
        A,
        B
    }
    public Test (TestEnum a = TestEnum.A)
    {
        DoSomething ();
    }

    protected void DoSomething()
    {
    }
}

The compiler (this is using Mono in a Unity3D project, .NET4.0 target) gives an error on the call in Test() to DoSomething() . If I remove the default parameter on TestEnum a , it builds just fine. MonoDevelop wants to call the default parameter TestEnum<>.A , but that doesn't compile, neither does TestEnum<T>.A (obviously I wouldn't have expected these to work but using MonoDevelop's autocomplete that's what I get).

EDIT: the specific error is: the name DoSomething doesn't exists in the current context

As said so in the comments, this is a compiler bug.

It seems as your Mono development environment doesn't really like the protected keyword.

Use {public,private} for now.
