错误注入类型“T”必须可转换为“T”才能在泛型方法中将其用作参数“T”

我有这个代码

public class NinjectControllerFactory : DefaultControllerFactory
{
    private IKernel ninjectKernel;
    public NinjectControllerFactory()
    {
        ninjectKernel = new StandardKernel();
        AddBindings();
    }
    protected override IController GetControllerInstance(
        RequestContext requestContext, Type controllerType)
    {
        return controllerType == null
            ? null
            : (IController)ninjectKernel.Get(controllerType);
    }
    private void AddBindings()
    {
        ninjectKernel
            .Bind<ICollection>().
            To<ListOfProcess.ConnectionLogic.ConnectionLogic>();
    }
}

并在最后一行出现下一个错误： 类型"T"必须可转换为"T"才能在泛型方法中将其用作参数"T"。
