+# WebClientService for .NET Core
+
+The WebClientService package provides a robust and flexible web client component designed to be used as a service within .NET Core applications. It leverages the power of '**IHttpClientFactory**' to facilitate efficient and scalable interactions with web services. This package supports dependency injection, making it easy to integrate into your existing .NET Core applications.
+
+## Key Features:
+- **Dependency Injection**: Seamlessly integrates with the .NET Core dependency injection framework.
+- **HTTP Client Management**: Utilizes '**IHttpClientFactory**' for robust HTTP client instantiation and management.
+- **Result Handling**: Comprehensive handling of HTTP response results with detailed status and error information.
+- **Extensible Base Classes**: Abstract base classes for implementing services that interact with web endpoints, returning various data types including strings and streams.
+- **Configurable Requests**: Supports various HTTP methods, custom headers, bearer token authentication, and more.
+
+## Usage Scenarios:
+- Consuming RESTful APIs
+- Fetching data from web services
+- Handling HTTP responses with rich error information
+- Streaming data from endpoints
+
+## Getting Started:
+
+1. **Installation**: Install the package via NuGet Package Manager.
+
+```shell
+dotnet add package WebClientService
+```
+
+2. **Configuration**: Configure IHttpClientFactory in your Startup.cs.
+
+```C#
+public void ConfigureServices(IServiceCollection services)
+{
+    services.AddHttpClient();
+    services.AddScoped<WebClientStringDataService>();
+    services.AddScoped<WebClientStreamDataService>();
+}
+```
+
+3. **Usage**: Inject the service into your controllers or services and start making web requests.
+
+```C#
+public class MyService
+{
+    private readonly WebClientStringDataService _webClient;
+
+    public MyService(WebClientStringDataService webClient)
+    {
+        _webClient = webClient;
+    }
+
+    public async Task<string> GetDataAsync(Uri requestUri)
+    {
+        var result = await _webClient.InvokeRequest(requestUri);
+        if (result.Result == RequestInvocationResultTypes.Ok)
+        {
+            return result.Data;
+        }
+        else
+        {
+            // Handle error
+            throw new Exception(result.Message);
+        }
+    }
+}
+```
