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 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.AddControllersAsServices(); <-- Add this line
    ...
}
