in preview azure ad b2c can define applications. each application given name, client id, app key , few settings define whether include web app / web api , whether allow implicit flow. in 'old' world of azure ad had greater control interaction between applications such "this application can access graph api", or "this application can talk service" whereas in new world order doesn't appear possible (at least portal ui perspective). question is: given lack of apparent control in azure ad b2c infrastructure has growing number of microservices, make sense create 'application' per service in azure ad b2c (and indeed per environment)? or should whole system share same application (and therefore client id?). (i comment on current score not allow me that) what do: have client ids each web , api app (container micro services). when initializing authentication api apps put client ids allowed talk api in validaudiences : public static st...
