We recently did a PI AF version upgrade to 2.10 from 2.9 post which a custom application which used AFSDK dll v 2.9 started giving build errors with certain methods.
1. Seems not to find the namespace using OSIsoft.AF.PI; anymore.
2. IEnumerable<PIPoint> points; - doesn't work.
3. PIServers piServers = new PIServers(); - Underline ones doesn't work.
Any help on what has been changed and how to fix these?
