Mark assemblies with CLSCompliant (deprecated)

Rule ND2201 .NET Framework Usage / System

Deprecated, disabled by default; re-enable if it fits your environment.

The Common Language Specification (CLS) defines rules assemblies must follow for cross-language use. Assemblies should explicitly indicate CLS compliance with CLSCompliantAttribute (absent = not compliant); a compliant assembly may still contain non-compliant members. Matches assemblies not tagged with System.CLSCompliantAttribute.

How to fix

Tag the assembly with CLSCompliantAttribute. Rather than marking the whole assembly non-compliant, mark the specific non-compliant members, ideally providing CLS-compliant alternatives for the widest audience.
