为什么NuPack生成的NinjectMVC3.cs无法编译？(或者ASP.NET MVC 3 Beta中的MvcServiceLocator发生了什么？)

Question

使用NuPack插件并安装NInject MVC 3包会导致生成的NinjectMVC3.cs文件中出现以下编译错误.

The name 'MvcServiceLocator' does not exist in the current context

David Ebbo发布的示例视频显示它在09:43运行得很好.

这是当前生成的类:

public class NinjectMVC3 {
    public static void RegisterServices(IKernel kernel) {
        //kernel.Bind<IThingRepository>().To<SqlThingRepository>();
    }

    public static void SetupDependencyInjection() {
        // Create Ninject DI Kernel 
        IKernel kernel = new StandardKernel();

        // Register services with our Ninject DI Container
        RegisterServices(kernel);

        // Tell ASP.NET MVC 3 to use our Ninject DI Container 
        MvcServiceLocator.SetCurrent(new NinjectServiceLocator(kernel));
    }
}

Answer 1

基本上,MvcServiceLocator已经消失了.我想,每当制作视频时,版本都会出现版本不匹配的情况.

这里和这里有很好的解释.

使Ninject工作的两个步骤如下.替换NinjectMVC3为以下(我也更改了不必要的名称):

public class NinjectResolver : IDependencyResolver
{
    private static IKernel kernel;

    public NinjectResolver()
    {
        kernel = new StandardKernel();
        RegisterServices(kernel);
    }

    public static void RegisterServices(IKernel kernel)
    {
        //kernel.Bind<IThingRepository>().To<SqlThingRepository>();
    }

    public object GetService(Type serviceType)
    {
        return kernel.TryGet(serviceType);
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return kernel.GetAll(serviceType);
    }
}

和下面的行添加到App_Start()在gloabl.asax.cs

DependencyResolver.SetResolver(new NinjectResolver());

我修复了包并将其上传到Feed.如果你有机会尝试并验证它现在有效,那就太好了.我将Ninject.MVC3的版本从0.1增加到0.2 :)
