是.NET“下面是所有COM”？ [英] Is .NET "all COM underneath"?

问题描述

多年来，我一直是Juval Lowy在.NET开发领域的教学和指导的仰慕者。他也写了我最喜欢的书之一：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.

然而，在最近的DotNet Rocks播客（2010年1月）讨论WCF / COM和.NET时，他做了一些评论，使我非常惊讶：

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

JuvalLöwy： ..... 在.NET，lo
中，每个类都是一个COM
对象。我们知道。实际上，它比COM更多，因为我们有
有git编译，我们有垃圾收集，
我们有安全堆栈... 。

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....

Carl Franklin：你应该澄清一下
。我的意思是，每个
对象不是一个COM对象。每个
对象具有COM
对象的功能，但.NET Framework
不是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.

JuvalLöwy：否，不。首先.NET实际上建立在COM的
顶部。

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

然后，在Carl Franklin要求澄清此评论后：

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

Carl Franklin：是的，我明白了。我的
问题是.NET上建立在COM？

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

JuvalLöwy：当然，所有COM
。

Juval Löwy: Of course, it all COM underneath.

Carl Franklin：不，我知道这是
交织在一起，是必需的，但是
.NET对象你是
不创建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.

JuvalLöwy：您正在创建一个.NET对象，但所有
我说的是.NET被构建
下面。它都是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.

Carl Franklin：它是C ++，但是您不是
通过
COM接口注册COM对象。这不是所有的东西
除非你特别这样做。

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.

JuvalLöwy：但是有些东西在下面使用
COM，但是在
点之外。

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

如何阅读这些评论？ >虽然我理解（并已经确认）一些系统程序集是用非托管C ++编写的，但是它也是有效的，说它们是所有COM在下面？

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"?

我假设完全可以编写与.NET / ATL / ActiveX完全无关的.NET CLI兼容C ++程序集。

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?

这是有关播客的 PDF文字 。参见第7页。

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

推荐答案

这几乎就像Löwy故意试图在他说的话不清楚。我没有听播客，但根据乌姆勒斯的评价，我估计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.

在.NET中使用的一些对象确实是COM对象的包装器。和你创建的.NET对象做了很多COM应该做和更多，没有COM的讨厌的烦恼。我不认为声明它是所有COM下面是准确或清楚。

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.

我希望采访过Jeff Richter。 ; - ）

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