I've found a lot of pages about CLS compliance.
I've understood that CLS compliance:
- Is a way to guarantee different assembly compatibility.
- Is a way to declare the high security code
Many peolple write that "if you write code, you should write it CLS compliant." But as far I can read, there is no reason to use CLS compliance in generic software.
Am I right, or did I miss something?
回答1:
If you write a library or framework it makes sense to ensure your library can be used from any CLR language.
回答2:
CLS-compliance is particularly important if you're distributing libraries - specifically, writing CLS compliant guarantees that your libraries will be usable by all CLS-compliant languages.
For instance, Visual Basic is not case-sensitive, whereas C# is. One of the requirements of CLS compliance is that public (and protected) member names should not differ only by case, thus ensuring that your libraries can be used safely by Visual Basic code, or any other .NET language that doesn't differentiate based on case.
回答3:
The answer is to allow maximum compatibility across .NET languages. CLS is the lingua franca that allows C# assemblies to work with F#, Iron Python, C++/CLI, VB.NET, Boo and all the other .NET languages. Step outside that boundary and your assembly may work correctly, but not necessarily.
回答4:
There may not be a specific reason to have your code be CLS compliant, but people are referring to it being a "best practice"--something that you should do because it's a good habit, rather than being measurably better for a particular scenario.
In other words, it's a good idea to make your code CLS compliant unless you have a reason not to.
