by default when enable swagger in asp.net core project it's available on url: http://localhost:<random_port>/swagger/ui i use different base url instead of /swagger/ui . how/where can configure that? i found older versions can configure rooturl there aren't similiar method in asp.net core: .enableswagger(c => { c.rooturl(req => mycustombasepath); }); the useswaggerui() extension method enable middleware in configure method of startup class takes 2 variables. baseroute on swagger/ui default, , swaggerurl on swagger/v1/swagger.json default. provide different baseroute. //swagger available under '/api' url app.useswaggerui("api"); if people learn more configuring swagger asp.net core, i've written blogpost started: https://dannyvanderkraan.wordpress.com/2016/09/09/asp-net-core-1-0-web-api-automatic-documentation-with-swagger-and-swashbuckle/

(this can done maintaining minimum required version on rest service). possible maintain minimum required version on play store? force user upgrade if current version < min required version. (redirecting user app store , not letting them app till upgrade - looking code pointers case) note different push notifications app store upgrades. unlike push notifications, logic allow app stay @ min version across user base. you can check current version of app using following code if using android studio. int versioncode = buildconfig.version_code; string versionname = buildconfig.version_name; i don...
