Yes and no :-) I want to use the original extension property, but need few more properties in the Patient resource e.g. _myBirthDate. I wanted to add them without modify the original  HS.FHIR.Model.Resource.Patient class  As HS.FHIR.Model.Datatype.Integer so they inherits extension property.

Thanks

Hi there,

I'm referring to new extensions. For example _birthDate or _randomExtension. I know the easiest way is to add them as a property of  HS.FHIR.Model.Resource.Patient, but I prefer to not to modify this class. Should I use  HS.FHIR.Model.Base.DomainResource  extension property for them?

Thanks for helping
