Mark assemblies with ComVisible (deprecated)

Rule ND2202 .NET Framework Usage / System

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

ComVisibleAttribute determines how COM clients access managed code; assemblies should indicate COM visibility explicitly (absent = visible to COM clients), overridable per type and member. Matches assemblies not tagged with System.Runtime.InteropServices.ComVisibleAttribute.

How to fix

Tag the assembly with ComVisibleAttribute, value false if it shouldn't be visible to COM clients.
