Base type is not CLS-compliant, what reasons of this warning?

Question

I have got warning from subject on one of my classes. Actually class is very simple, just an inheritor of my generic base type. Also I have some other inheritors from that g

I guess you have a derived type marked as CLSCompliant but the base isn't.

Writing CLS Compliant Code The canonical example is using a UInt32 which is not part of the Common Language Specification (CLS) - hence you need to use Int64 to be CLS compliant or remove the attribute (declare yourself non-cls compliant).

Need more code to identify the offending line of code. More info on the error you're getting.
