C#揭密II（大师们在说些什么？）

先声明这篇文章属于收藏性质的,推荐给那些喜欢dotNET技术的爱好者。
这之前我曾转载了O'Reilly的一篇关于C#的访谈录。O'Reilly一向以技术和评论公见长，他们的编辑一般都有着很深的技术背景和功力(所以出的书也比较贵haha)，所以那篇着重整个流行技术，有不少是和Java相关的；而这一篇都是MS内部的几个高手在交谈聊天，涉及的范围比上次的专访要广，里面有一些很新奇的术语和许多问题的观点。另外我认为这篇文章对以前非常熟悉COM+、ASP和Window DNA（N 层结构）的人目前评估和思考向新的dotNET体系迁移都很有帮助。

Anders Hejlsberg是个很奇怪的人，从他身上你感觉不到一个程序语言创始人那种对某种语言偏爱的狂热，却很容易感觉到他所透露出的那种对技术对程序语言的坚定和深厚理解。很喜欢他在上一篇访谈录中说的一句话：“Language is a funny thing: It's a matter of taste. Language is almost a religious thing, and it's a lifestyle choice for programmers。”不过我知道这句话说的不是他自己。这篇文章中还有好些人：Brian Harry，Peter Golde ，Scott Guthrie（ASP老怪），Mark Anders。有了这些人，Microsoft有福啊。

Conversations on .NET


Derived from on-line chats with our early adopters, a series of conversations with Microsoft engineers, designers, and developers look at issues involving C#, ASP.NET, and the Common Language Runtime.

Summary: What follows is a series of conversations with Microsoft engineers, designers, and developers, looking at issues involving C#, ASP.NET, and the Common Language Runtime. (10 printed pages)

A Conversation with Anders Hejlsberg and Peter Golde on C#

Anders Hejlsberg is a Distinguished Engineer in the Developer Division at Microsoft Corporation. He is the chief designer of the C# programming language and a key participant in the development of the .NET Framework. Previously, Anders was the architect for Visual J++ and the Windows Foundation Classes.

Peter Golde is a Software Design Engineer in the Developer Division at Microsoft Corporation. Peter has worked on development tools at Microsoft for over 10 years, contributing to products such as Microsoft C, OLE Automation, Visual Basic, Visual Basic for Applications, and Visual J++.

Q: Peter, you attended the ECMA meetings in March. Can you disclose anything about what's going on there that is new?

Peter Golde: Sure. As some of you may know, Microsoft, Intel, and HP jointly submitted two specifications to ECMA for standardization via the ECMA process. These two specifications are the C# language and the common language infrastructure (CLI), which is a subset of the .NET Framework. We're meeting with a number of companies every month as part of the standardization process. It's difficult to predict the schedule with absolute certainty, but we hope that ECMA will be able to complete standards for both parts by the end of 2001.

Q: How does the CLI compare to the CLS and the CTS?

Anders Hejlsberg: CLS stands for Common Language Specification, CTS stands for Common Type System. The CLS is a specification of what features any programming language implemented on the .NET platform must support.

Q: OK, the CLS is less than the CTS. Where does the CLI fit?

Anders Hejlsberg: The CTS is basically another word for the type system in .NET, i.e. a specification of what a class, struct, enum, or such is. CLI is really just another word for the large subset of the .NET Framework that we submitted to ECMA.

Peter Golde: The CLI includes the CLS and the CTS.

Q: Anders, after your work on Turbo Pascal, Delphi, Visual J++ and now C#, how do you see programming languages evolving today?

Anders Hejlsberg: Jeeez, had to ask an easy one, eh? I guess I'm becoming less and less of a believer in revolutionary approaches to language design. It really is amazing how much the capabilities of computing have evolved, yet we're basically still using the same kinds of programming languages. It gives me hope that we can go even further with an evolutionary approach where we don't just invalidate all the work that went before.

Q: Have you thou
