Unity.Microsoft.DependencyInjection

Unity extension to integrate with Microsoft.Extensions.DependencyInjection compliant systems

Getting Started

• Reference the Unity.Microsoft.DependencyInjection package from NuGet.

Install-Package Unity.Microsoft.DependencyInjection

Registration:

• In the WebHostBuilder add UseUnityServiceProvider(...) method

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
           .UseUnityServiceProvider()   <---- Add this line
           .UseStartup<Startup>()
           .Build();

• In case Unity container configured via application configuration or by convention this container could be used to initialize service provider.

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
           .UseUnityServiceProvider(_container)   <---- or add this line
           .UseStartup<Startup>()
           .Build();

• Add optional method to your Startup class

public void ConfigureContainer(IUnityContainer container)
{
  // Could be used to register more types
  container.RegisterType<IMyService, MyService>();
}

Resolving Startup

Startup class instance is resolved from Unity if it is configured as default container.

Resolving Controllers from Unity

By default ASP resolves controllers using built in activator. To enable resolution of controllers from Unity you need to add following line to MVC configuration:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc()
            .SetCompatibilityVersion(CompatibilityVersion.Version_xxx) 
            .AddControllersAsServices(); <-- Add this line
}
