+## Alternative: Using LocalStack.NET
+
+If you're working with .NET and LocalStack, you have a few options. In addition to the AWS SDK for .NET, there's an alternative client library, `LocalStack.NET`, which facilitates integration with LocalStack.
+
+### Overview
+
+`LocalStack.NET` is a .NET client library developed to simplify the connection between .NET applications and LocalStack. It wraps around the AWS SDK for .NET and offers an alternative setup for creating LocalStack clients.
+
+**LocalStack.NET Documentation:** Comprehensive guide and examples [here](https://github.com/localstack-dotnet/localstack-dotnet-client).
+
+### How it Works
+
+- Instead of manually setting the endpoint configurations when initializing a client, `LocalStack.NET` offers methods that handle these details.
+- The library aims to reduce the boilerplate required to set up LocalStack clients in .NET.
+
+### Example Usage
+
+#### Dependency Injection Approach
+
+```csharp
+public void ConfigureServices(IServiceCollection services)
+{
+    // Add framework services.
+    services.AddMvc();
+
+    services.AddLocalStack(Configuration)
+    services.AddDefaultAWSOptions(Configuration.GetAWSOptions());
+    services.AddAwsService<IAmazonS3>();
+}
+
+...
+
+var amazonS3Client = serviceProvider.GetRequiredService<IAmazonS3>();
+```
+
+#### Standalone Approach
+
+```csharp
+var sessionOptions = new SessionOptions();
+var configOptions = new ConfigOptions();
+
+ISession session = SessionStandalone.Init()
+                                .WithSessionOptions(sessionOptions)
+                                .WithConfigurationOptions(configOptions).Create();
+
+var amazonS3Client = session.CreateClientByImplementation<AmazonS3Client>();
+```
+
+### Benefits
+
+- **Consistent Client Configuration:** `LocalStack.NET` provides a standardized approach to initialize clients, eliminating the need for manual endpoint configurations.
+- **Tailored for .NET Developers:** The library offers functionalities specifically developed to streamline integration of LocalStack with .NET applications.
+- **Adaptable Environment Transition:** Switching between LocalStack and actual AWS services can be achieved with minimal configuration changes when leveraging `LocalStack.NET`.
+- **Versatile .NET Compatibility:** Supports a broad spectrum of .NET versions, from .NET Framework 4.6.1 and .NET Standard 2.0, up to recent .NET iterations such as .NET 7.0.
+
+### Considerations:
+
+- Both the standard AWS SDK method and `LocalStack.NET` provide ways to integrate with LocalStack using .NET. The choice depends on developer preferences and specific project needs.
+- `LocalStack.NET` works alongside the AWS SDK, using it as a base and providing a more focused API for LocalStack interactions.
