Hey, how does one add a list of complex type extensions to an extension?
Specifically, how would you go about creating the norwegian practitioner profile via dotnet pocos?

GD-Practitioner: https://simplifier.net/grunndata/gd-practitioner-v01-duplicate-2

What I'm after is how to create: Practitioner.qualification.specialty if I have say 10 specialities I want to put into the specialty extension.

All PoCo classes in the dotNET API provide a common Extensions collection. First create and initialize an instance of the desired extension (e.g. specialty). Then you can add the initialized extension instance to the Extensions collection of the target element in the receiving profile.

Nice! Thanks for the quick reply :) I sorta thought of the url as a key, and therefore had a mindblock of adding multiple extensions using the same url to an extension. Wrote a quick test using the R4 Citizenship for Patient and it works flawlessly.

Keep up the good work!

No problem.
The specific practitioner profile (https://simplifier.net/grunndata/gd-practitioner-v01-duplicate-2) defines the Practitioner.qualification.specialty extension element with cardinality 0...*, stating that it is valid for an instance to contain a list of specialties.
In the .NET FHIR API, the Element.Extension collection is modeled as a List<T>, i.e. not as a keyed collection. The Extension.url child element value represents the canonical url of the associated extension definition.
In your case, repeated specialty values on an instance element will all refer to the same canonical url of the specialty extension definition.

Interesting design Michel, @Brett Esler we should look at this for the AU profiles along with comparing to the VhDir guide. Which extends the qualification too
