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 IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .UseUnityServiceProvider()   <---- Add this line
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

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

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .UseUnityServiceProvider(_container)   //<---- Add this line
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

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.AddMvc()
        .AddControllersAsServices()  //<-- Add this line
        .SetCompatibilityVersion(CompatibilityVersion.Version_3_0)
    ...
}
