I'm building my first pro add-in and am currently in the initial stages. I have my tab, groups, and buttons setup. I want to change the button graphics but am having trouble understanding where to get the standard ESRI images. There is a link here DAML ID Reference Icons · Esri/arcgis-pro-sdk Wiki · GitHub but not certain how to view the images within Visual Studio.
Second question is about best practices for Windows Forms within my add-in. with ArcMap i displayed a Form for each of my functions. What is the best practices for Pro? Is it to use the Pro built in panels? Or what object should I use to display to the user? Some of my forms require quite a bit of input.
