In ArcObjects, I have an IProjection object using the predefined projections and I am looking for a way to apply it to the map. So this is the pseudocode that I'm looking to do with the projection objection predefined as "projection" and the focus map set as "map"
map.projection = projection;
Granted I understand that this is oversimplified but I can't find the documentation on how to do this anywhere.
Any help is greatly appreciated. And I am using C#
