如何在MVC5中使用实体框架实现依赖注入

public DbSet<Product> Products { get; set; }

protected void Application_Start()
{
    // ...
    DependencyResolver.SetResolver(new AutofacDependencyResolver(RegisterServices()));
    // ...
}

private static IContainer RegisterServices()
{
    var builder = new ContainerBuilder();

    // 注册DbContext
    builder.RegisterType<YourDbContext>().As<DbContext>().InstancePerRequest();

    // 注册其他依赖项
    // builder.RegisterType<YourService>().As<IYourService>().InstancePerRequest();

    return builder.Build();
}

public class ProductController : Controller
{
    private readonly DbContext _dbContext;

    public ProductController(DbContext dbContext)
    {
        _dbContext = dbContext;
    }

    // ...
}
