For more information, see Kestrel endpoint configuration Read the port from environment The following command makes the app respond to port 7777: dotnet run -urls=" If the Kestrel endpoint is also configured in the appsettings.json file, the appsettings.json file specified URL is used. var app = WebApplication.Create(args) Īpp.Urls.Add(" (" app.MapGet("/", () => "Hello World") In the following code, the app responds to port 30. var app = WebApplication.Create(args) Īpp.Run(" In the preceding code, the app responds to port 3000. The following sections set the port the app responds to. Visual Studio returns an error because it's expecting the port specified in Properties/launchSettings.json, but the app is using the port specified by app.Run(" Run the following port changing samples from the command line. In the port setting samples that follow, running the app from Visual Studio returns an error dialog Unable to connect to web server 'AppName'. When a web app is created with Visual Studio or dotnet new, a Properties/launchSettings.json file is created that specifies the ports the app responds to. Terminal middleware is middleware that runs if no endpoint handles the request. The app needs to call UseRouting and UseEndpoints so that the terminal middleware can be placed at the correct location.The middleware must be added after UseEndpoints.UseEndpoints isn't required in this case as it is automatically added as described previously: app.Use((context, next) => If middleware should be run before route matching occurs, UseRouting should be called and the middleware should be placed before the call to UseRouting. The app needs to call UseAuthentication and UseAuthorization if UseCors is called: app.UseCors() For example, UseCors should be called before UseAuthentication and UseAuthorization. In some cases, the default middleware configuration isn't correct for the app and requires modification. The following code is effectively what the automatic middleware being added to the app produces: if (isDevelopment) User configured middleware and endpoints are added between UseRouting and UseEndpoints.IAuthorizationHandlerProvider is added by default when using AddAuthorization, and services are detected using IServiceProviderIsService. UseAuthorization is added next if user code didn't already call UseAuthorization and if IAuthorizationHandlerProvider can be detected in the service provider.IAuthenticationSchemeProvider is added by default when using AddAuthentication, and services are detected using IServiceProviderIsService. UseAuthentication is added immediately after UseRouting if user code didn't already call UseAuthentication and if IAuthenticationSchemeProvider can be detected in the service provider.UseEndpoints is added at the end of the middleware pipeline if any endpoints are configured.UseRouting is added second if user code didn't already call UseRouting and if there are endpoints configured, for example app.MapGet.UseDeveloperExceptionPage is added first when the HostingEnvironment is "Development".WebApplication automatically adds the following middleware depending on certain conditions:
