我一直Juval洛伊的教学和指导的.NET开发了数年的崇拜者。他还写了我最喜欢的一本书：编程.NET组件。

I've been an admirer of Juval Lowy's teaching and guidance in .NET development for a number of years. He's also written one of my favorite books: Programming .NET Components.

不过在最近的一个DOTNET的岩石播客（2010年1月）在讨论WCF / COM和NET中，他提出了一些意见，大大出乎我的意料：

However on a recent DotNet Rocks podcast (Jan 2010) in discussing WCF/COM and .NET, he made some comments that greatly surprised me:

Juval洛伊： ..... 在.NET中，罗   看哪，在这里的每类是一个COM   目的。我们知道这一点。事实上，它比COM更因为我们已经   得到了git的编译，我们已经有了垃圾收集，   我们已经得到了安全堆栈....

Juval Löwy: ..... in .NET, lo and behold, every class here is a COM object. We know that. In fact, it's much more than COM because we've got the git compiling, we've got garbage collection, we've got the Security Stack....

卡尔·富兰克林：那么，你应该澄清的是，   虽然。我的意思是，每   对象不是一个COM对象。所有的   对象具有的功能，一个COM   对象的做法，但在.NET Framework   是不是一个COM库。

Carl Franklin: Well, you should clarify that though. I mean, every object is not a COM object. Every object has the capabilities that a COM object does, but the .NET Framework isn't a COM library.

Juval洛伊：不，不。首先，.NET的实际上是建立在   COM的顶部。这是所有的COM下面。

Juval Löwy: No, no. First of all .NET is actually built on top of COM. It's all COM underneath.

随后，在卡尔·富兰克林要求澄清此评论：

Then, after Carl Franklin asks for clarification on this comment:

卡尔·富兰克林：是啊，我明白了。我的   问题是在.NET建立在COM？

Carl Franklin: Yeah, I get that. My question was is .NET built on COM?

Juval洛伊：当然，这一切的COM   下方。

Juval Löwy: Of course, it all COM underneath.

卡尔·富兰克林：不，我知道这是   相互缠绕和它的要求，但   当你新的一个.NET对象你   没有创造一个COM对象。

Carl Franklin: No. I know it's intertwined and it's required, but when you new up a .NET object you're not creating a COM object.

Juval洛伊：您正在创建一个.NET对象，但都   我的意思是，.NET是建立   下。这是所有的C ++和COM。

Juval Löwy: You're creating a .NET object, but all I'm saying is that .NET is built underneath. It's all C++ and COM.

卡尔·富兰克林：这是C ++，但你不   通过注册的COM对象   COM接口。这是不是所有的东西   除非你专门做。

Carl Franklin: It is C++ but you're not registering a COM object through the COM interface. It isn't all that stuff unless you specifically do that.

Juval洛伊：但是有些东西是用   COM下，但是这是旁边的   点。忘掉制造的原理。

Juval Löwy: But some of the stuff is using COM underneath, but that's beside the point. Forget about how it's made.

你怎么看这些评价？

虽然我知道（和已确认），一些系统组件都写在非托管C ++，是不是也有效地说，他们是下的所有COM？

While I understand (and have confirmed) that some of the System assemblies are written in unmanaged C++, is it also valid to say that they are "all COM underneath"?

我的假设是完全可以编写.NET CLI标准的C ++组件有绝对无关，与COM / ATL / ActiveX技术？

I was under the assumption it is perfectly possible to write .NET CLI compliant C++ assemblies that have absolutely nothing to do with COM / ATL / ActiveX?

下面是 PDF成绩单有问题的播客。见第7页。

Here is the PDF transcript for the podcast in question. See Page 7.

推荐答案

这几乎就像洛伊故意试图不清楚他说的话。我没有听播客，而是由变音的情况来看，我觉得英语不是他的第一语言。

It's almost as if Löwy is intentionally attempting to be unclear in what he says. I've not listened to the podcast, but judging by the umlauts, I reckon English is not his first language.

您在.NET中使用的一些对象真的是包装COM对象。你创建一个.NET对象做了很多COM什么是应该做的多，没有COM的讨厌的烦恼。我不认为声明这下所有的COM是准确或清楚的。

Some objects that you use in .NET really are wrappers for COM objects. And a .NET object you create does a lot of what COM is supposed to do and more, without COM's nasty annoyances. I don't think the statement "it's all COM underneath" is accurate or clear.

我希望采访中曾与杰夫里氏。 ; - ）

I wish the interview had been with Jeff Richter. ;-)
