FunctionLinkBuilder.CreateFunctionLinkFactory Method (Func<EntityInstanceContext, Uri>, Func<EntityInstanceContext, Boolean>)

Creates an function link factory that builds an function link, but only when appropriate based on the expensiveAvailabilityCheck, and whether expensive checks should be made, which is deduced by looking at the EntityInstanceContext.SkipExpensiveFunctionAvailabilityChecks property.
