.NET API
§Preferences moved out of BuildingServices
§Each domain now has their own preferences
§HVAC
§Piping
§Electrical (present previously)
§Plumbing (present previously)
§DbVars will be removed in favor of preferences
§
In the API specifics, preferences have moved. Most of the preferences were contained in BuildingServices preferences class at the application level. To make them easier to manage, the domain based preferences have been reorganized and moved to to domain specific classes.  HVAC and Piping have their own specific preference class. Electrical and Plumbing previously were moved. Now it is consistent across the board. Each domain has its own set of preferences. DbVars will be removed in favor of using preferences class instead.
