chris31389 answers the questions Pinpointtownes ask, as follows:

PublicClassstartup{public void configureservices ( Iservicecollection services) {services. Addauthentication (options = options. Defaultscheme = Jwtbearerdefaults.authenticationscheme; }) . Addjwtbearer (options = options. authority =  "Http://localhost:30940/"; Options. Audience =  "Resource-server"; Options. Requirehttpsmetadata = false;}); } public void configure ( Iapplicationbuilder app) {app. Useauthentication (); //...}

Services. Addauthentication (options ={options. Defaultscheme=Jwtbearerdefaults.authenticationscheme; })       . Addjwtbearer (Options={options. Tokenvalidationparameters=Newtokenvalidationparameters {Issuersigningkey=Tokenauthoption.key, Validaudience=tokenauthoption.audience, Validissuer=Tokenauthoption.issuer, Validateissuersigningkey=true, Validatelifetime=true, Clockskew= Timespan.fromminutes (0),           }; });
