Questions tagged [cls-compliant]

The CLS (Common Language Specification) is a set of constraints on APIs and a complementary set of requirements on languages. If a library is CLS-compliant (i.e. adheres to all the constraints), then any CLS-compliant language can use that API. Conversely, a CLS-compliant language is guaranteed to be able to use any CLS-compliant library. (Int32 is an example of a CLS-compliant type, so CLS guarantees it's safe for library writers to use it in their APIs.)

Are there any non CLS compliant .NET languages in common use?

Are there any non CLS compliant .NET languages in common use these days? It looks like every managed language that ships out of the box with VS2012 supports unsigned integer types, so practically speaking how much trouble is one likely to get into…

I am witnessing some odd behaviour with mshtml and CLS-compliance. I have an assembly marked CLSCompliant(true). This assembly does not expose any types from mshtml publicly. I can make the code conform to CLS fairly easily, but several things seem…
