title: In which nuget package is IApplicationBuilder extension UseEndpoints?
body: <p>I'm trying to create a middleware library and want to include routing, so have added <code>Microsoft.AspNetCore.Routing</code> but the <code>UseEndpoints</code> extension isn't available. If I add the mega package <code>Microsoft.AspNetCore.App</code> then it's fine, but I don't want to include all the things. Thanks!</p>
