. NET, have you forgotten (a)--CLS-compliant

First, let's simply look at what is called the CLS.

In view of the personal English level, I will give the CLS the English explanation first, then I translate again:

The CLS is a specification which defines the rules to support language integration. This is doing in such a way, which programs written in any language (. NET compliant) can interoperate with one another. This also can take all advantage of inheritance, polymorphism, exceptions, and other features.

The CLS defines a specification that supports language inheritance, which enables us to interact with any of the. NET-compatible languages, which allows you to take advantage of inheritance, polymorphism, exceptions, and other features.

In fact, it is simplified to say that the CLS is defined as a subset of the language to ensure the interoperability of the language.

Therefore, in order to interoperate between languages, we should make our programs CLS-compliant.

Let's look at the hierarchy of the system, the system should be the assembly, the Assembly is the class (or structure, etc.). So in order to ensure the interoperability of the language, we should ensure that the external parts of the assembly are CLS-compliant.

This is an easy guarantee:

When we create a new assembly, there is a file called: AssemblyInfo.cs:

[assembly:　AssemblyTitle("ClassLibrary1")]
[assembly:　AssemblyDescription("")]
[assembly:　AssemblyConfiguration("")]
[assembly:　AssemblyCompany("微软中国")]
[assembly:　AssemblyProduct("ClassLibrary1")]
[assembly:　AssemblyCopyright("Copyright　©　微软中国　2009")]
[assembly:　AssemblyTrademark("")]
[assembly:　AssemblyCulture("")]

//　将　ComVisible　设置为　false　使此程序集中的类型
//　对　COM　组件不可见。如果需要从　COM　访问此程序集中的类型，
//　则将该类型上的　ComVisible　属性设置为　true。
[assembly:　ComVisible(false)]

//　如果此项目向　COM　公开，则下列　GUID　用于类型库的　ID
[assembly:　Guid("694543e8-4c7f-4952-9e98-7282ecff1c15")]

//　程序集的版本信息由下面四个值组成:
//
//　　　主版本
//　　　次版本　
//　　　内部版本号
//　　　修订号
//
//　可以指定所有这些值，也可以使用“内部版本号”和“修订号” 的默认值，
//　方法是按如下所示使用“*”:
//　[assembly:　AssemblyVersion("1.0.*")]
[assembly:　AssemblyVersion("1.0.0.0")]
[assembly:　AssemblyFileVersion("1.0.0.0")]
