 # PosInformatique.AspNet.WebForms.DependencyInjection
 PosInformatique.AspNet.WebForms.DependencyInjection is a library to add the IoC container support of Microsoft.Extensions.DependencyInjection for ASP .NET Web Forms
+
+## Installing from NuGet
+The **PosInformatique.AspNet.WebForms.DependencyInjection** is available directly on the
+[NuGet](https://www.nuget.org/packages/PosInformatique.AspNet.WebForms.DependencyInjection/) official website.
+To download and install the library to your Visual Studio project using the following NuGet command line 
+```
+Install-Package PosInformatique.AspNet.WebForms.DependencyInjection
+```
+
+## Setting up
+After adding the **PosInformatique.AspNet.WebForms.DependencyInjection** package on your ASP .NET
+WebForms project call the `AddServiceCollection` the following lines in the constructor of your `HttpApplication` class in the
+`Global.asax.cs` code behind:
+```csharp
+public class Global : HttpApplication
+{
+    public Global()
+    {
+        ServicesConfig.RegisterServices(this.AddServiceCollection());
+    }
+
+    void Application_Start(object sender, EventArgs e)
+    {
+        // Code that runs on application startup
+        RouteConfig.RegisterRoutes(RouteTable.Routes);
+        BundleConfig.RegisterBundles(BundleTable.Bundles);
+    }
+}
+```
+
+In the `App_Start` folder add a new static class called `ServicesConfig` which allows to register
+the services using the `Microsoft.Extensions.DependencyInjection.ServiceCollection`:
+```csharp
+namespace PosInformatique.AspNet.WebForms.DependencyInjection.IntegrationTests
+{
+    using System;
+    using System.Collections.Generic;
+    using System.Collections.ObjectModel;
+    using System.Linq;
+    using Microsoft.Extensions.DependencyInjection;
+
+    public static class ServicesConfig
+    {
+        public static void RegisterServices(ServiceCollection serviceCollection)
+        {
+            serviceCollection.AddSingleton<IDogRepository, DogRepository>();
+            serviceCollection.AddTransient<IDogManager, DogManager>();
+        }
+    }
+}
+```
+You can register services with a *Transient* or *Singleton* scope. Unlike to ASP .NET Core,
+**PosInformatique.AspNet.WebForms.DependencyInjection** does not support *Scoped* scope services
+which exists during the HTTP request lifetime.  
+
+## Contributions
+Do not hesitate to clone my code and submit some changes...
+It is a open source project, so everyone is welcome to improve this library...
+By the way, I am french... So maybe you will remarks that my english is not really fluent...
+So do not hesitate to fix my resources strings or my documentation... Merci !
+
+## Thanks
+I want to thank the [DiliTrust](https://www.dilitrust.com/) company to test and gave me their
+feedback of this library for their ASP .NET WebForms applications.
