blocks|key|3153889|text|.NET是运行时，C#是语言。C#可以在其他运行时编译和运行，比如Mono。实际上，除了Mono之外，我不知道还有其他的运行时，但由于C#的规范是开放的，你可以阅读它并创建自己的运行时。;)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3153890|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

.NET is the runtime and C# is the language. C# can be compiled and run on other runtimes, such as Mono. I am actually not aware of any other runtimes besides Mono, but since the spec for C# is open, you could read it and make your own runtime. ;)

blocks|key|1745382|text|ECMA确实对.NET运行时的各个部分进行了标准化，就像C#+-+CIL、CLI、CLS一样。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1745383|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Various parts of the .NET runtime are indeed standardised by ECMA just like C# - CIL, the CLI, the CLS.

blocks|key|3153969|text|与Java、C、C%2B%2B等一样，C#也只是一种语言定义。就其本身而言，它什么也不做。它定义了用户可以用来定义程序或过程以及与外部库接口的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3153970|另一方面，.NET框架不是一种语言。它是一个类库和开发框架。|3153971|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

C#, like Java, C, C++, etc. is just a language definition. In and of itself, it does nothing. It defines the means by which a user can define a program or procedure and interface with external libraries.

The .NET framework, on the other hand, is not a language. It's a class library and development framework.

blocks|key|392414|text|实际上，有一个开放的标准(用于运行时应用程序接口的ECMA+335，而不是用于该语言的ECMA+334+)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|392415|除此之外，还有the+source+code+for+Microsoft's+implementation+of+.Net+is+available和multiple+separate+implementations+(其中最突出的是mono)。|392416|还有一些关于专利负担的额外担忧。然而，微软也在.Net平台上发布了涵盖这两种规范的legally+binding+and+irrevocable+community+promise+(许多人错过了具有法律约束力的部分)。|392417|entityMap|0|LINK|mutability|MUTABLE|url|http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-335.pdf|1|http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-334.pdf|2|http://weblogs.asp.net/scottgu/archive/2008/01/16/net-framework-library-source-code-now-available.aspx|3|http://en.wikipedia.org/wiki/.NET_Framework#Alternative_implementations|4|http://www.mono-project.com/Main_Page|5|http://www.microsoft.com/interop/cp/default.mspx^0|P|8|0|17|8|1|0|7|1V|2|23|X|3|39|4|4|0|15|1D|5|0^^$0|@$1|2|3|4|5|6|7|Z|8|@]|9|@$A|10|B|11|1|12]|$A|13|B|14|1|15]]|C|$]]|$1|D|3|E|5|6|7|16|8|@]|9|@$A|17|B|18|1|19]|$A|1A|B|1B|1|1C]|$A|1D|B|1E|1|1F]]|C|$]]|$1|F|3|G|5|6|7|1G|8|@]|9|@$A|1H|B|1I|1|1J]]|C|$]]|$1|H|3|-4|5|6|7|1K|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]|P|$5|K|L|M|C|$N|Q]]|R|$5|K|L|M|C|$N|S]]|T|$5|K|L|M|C|$N|U]]|V|$5|K|L|M|C|$N|W]]|X|$5|K|L|M|C|$N|Y]]]]

Actually, there is an open standard (<a href="http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-335.pdf" rel="nofollow noreferrer">ECMA 335</a> for the runtime api instead of <a href="http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-334.pdf" rel="nofollow noreferrer">ECMA 334</a> for the language). 

Going beyond this, <a href="http://weblogs.asp.net/scottgu/archive/2008/01/16/net-framework-library-source-code-now-available.aspx" rel="nofollow noreferrer">the source code for Microsoft's implementation of .Net is available</a> and there are <a href="http://en.wikipedia.org/wiki/.NET_Framework#Alternative_implementations" rel="nofollow noreferrer">multiple separate implementations</a> (the most prominent of which by far is <a href="http://www.mono-project.com/Main_Page" rel="nofollow noreferrer">mono</a>).

There is some additional concern about patent encumbrance. However, Microsoft has also issued a <a href="http://www.microsoft.com/interop/cp/default.mspx" rel="nofollow noreferrer">legally binding and irrevocable community promise</a> on the .Net platform that covers both specifications (a lot of people miss the legally binding part).

blocks|key|1745507|text|我想你指的是框架。我猜他们想要保持对Windows上的库实现的控制。正如Mono所做的那样，没有什么可以阻止人们基于自己的源代码实现整个或部分框架的调用兼容版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1745508|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I assume you mean the framework. I guess they want to maintain control over the library implementation on Windows. There is nothing stopping someone from implementing a call-compatible version of all or part of the framework based on their own source as was done by Mono.

Why C# is an open standard but .NET is not? What is the point in this? Why Microsoft decide to open only some part of their .NET?
