ArcGIS Pro: 2.7
Visual Studio: 2017, 2019
The upgrade from ArcGIS Pro SDK 1.4 to ArcGIS Pro SDK 2.0 is a 'code breaking' change. This means that you have to change, recompile, rebuild, and redistribute any 1.x (SDK 1.4 and earlier) add-ins and configurations so that they work with ArcGIS Pro 2.0.
This document lists all 1.4 ProSnippets that required modification in order to work with ArcGIS Pro 2.0. The 1.4 code snippet is shown as the before code snippet and the equivalent 2.0 code snippet is shown as the now: code snippet.
With 2.0 the ItemFactory pattern changed notably as documented in ProConcepts Content and Items.
The following ProSnippet Migrations samples are available:
