IAoInitialize Interface (ArcObjects .NET 10.5 SDK)
ArcObjects Library Reference (System)  

IAoInitialize Interface

Provides access to members that initialize licensing for ArcGIS Desktop, Engine, and Server.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The IAoInitialize Interface is the starting point for developers to initialize each application with a suitable license(s) in order for it to run successfully on any machine it is deployed on to. License configuration must be undertaken at application start time, before any ArcObjects are accessed. Failure to do so will result in application errors.
