 If you have other applications such as ASP.NET in the entire project and want to use common DI and configuration set up using `Microsoft.Extensions.Hosting`, you can call `ToConsoleAppBuilder` from `IHostBuilder` or `HostApplicationBuilder`.
 
 ```csharp
-// Package Import: Microsoft.Extensions.Hosting

 var app = Host.CreateApplicationBuilder()
     .ToConsoleAppBuilder();

 ConsoleAppFramework has its own lifetime management (see the [CancellationToken(Gracefully Shutdown) and Timeout](#cancellationtokengracefully-shutdown-and-timeout) section), therefore it is handled correctly even without using `ConsoleLifetime`.
 
+If you want to use other DI container(like [DryIoc](https://github.com/dadhi/DryIoc)) without Microsoft.Extensions.Hosting, you can use `ConfigureContainer` and setup `IServiceProviderFactory`.
+
+```csharp
+// dotnet add package Microsoft.Extensions.DependencyInjection
+// dotnet add package DryIoc.Microsoft.DependencyInjection
+var app = ConsoleApp.Create()
+    // setup DryIoc as the DI container
+    .ConfigureContainer(new DryIocServiceProviderFactory())
+    .ConfigureServices(services => services.AddSingleton<MyService>());
+
+app.Add("", ([FromServices] MyService service) => { });
+
+app.Run(args);

 OpenTelemetry
 ---
 It's important to be conscious of observability in console applications as well. Visualizing not just logging but also traces will be helpful for performance tuning and troubleshooting. In ConsoleAppFramework, you can use this smoothly by utilizing the OpenTelemetry support of HostApplicationBuilder.
