Added module is not CLS-compliant, or is missing CLS-compliant attribute
A module that was compiled with the /target:module compiler option was added to a compilation via /addmodule. However, the module’s compliance with the Common Language Subset (CLS) does not agree with the CLS state of the current compilation.
CLS compliance is indicated with the module attribute. For example, [module:CLSCompliant(true)]
indicates that the module is CLS compliant, and [module:CLSCompliant(false)]
indicates that the module is not CLS compliant. The default is [module:CLSCompliant(false)]
