I hesitate to ask this question as I fear it will reveal a major part of the new ArcGIS Pro sdk that I probably should already be aware of . Specifically, I have been looking at the various help resources ( sdk reference, snippets, etc...) for an example of adding graphic elements and map surround type objects to a layout through code. Coming from ArcObjects I was looking for a pattern following the familiar ArcObjects IGraphicsContainer.
The Pro Layout Snippet examples appear to be confined changing elements already present in the layout. I have looked at the LayoutProjectItem as well the Layout class itself. I can see the method to return Elements from the pro Layout class. However, I have not figured out how to add new elements of even determine whether it is possible.
Any assistance would be appreciated.
