Unbound Type

[dashne]

how to check if a type is an unbound type (a generic type, but no type arguments were provided)

[Washi1337]

So an ordinary TypeDefinition with GenericParameters.Count > 0?

[dashne]

what if type argument is provided?

[Washi1337]

Then this would not have been a TypeDefinition instance but a GenericInstanceTypeSignature that is (potentially) wrapped in a TypeSpecification instance.
