迁移到 Visual Studio 2015 构造函数后 .create 丢失

Question

我安装了 Visual Studio 2015 Community 并尝试在此处打开两个项目，第一个运行良好，但第二个在 Global.asax.cs 中显示以下错误

错误如下所示：

出于某种原因，它没有找到 .Create 方法。但是，如果我在 Visual Studio 2013 中打开同一个项目，它可以正常工作。

我用.Net Framework 4.5 这些方法看起来像使用 OData.Entities

下面的代码是 class .AddressMapper()

public class AddressMapper : TimestampMapper, IMapper<AccountCustomerEntity, Address>
{
    public AddressMapper();  
    public void Map(AccountCustomerEntity accountCustomerEntity, Address address);
}

下面的代码显示了该方法：.WithAddressFn 和 parents。

public static class OrderMapperExtensions
{
    public static OrderMapper WithAccountFn(this OrderMapper mapper, Func<int, Account> accountFn);
    public static OrderMapper WithAddressFn(this OrderMapper mapper, Func<AccountCustomerEntity, Address> addressFn);
    public static OrderMapper WithArticleFn(this OrderMapper mapper, Func<RequisitionDeliveryDetailEntity, Article> articleFn);
    public static OrderMapper WithCarrierFn(this OrderMapper mapper, Func<int, Carrier> carrierFn);
    public static OrderMapper WithLineItemFn(this OrderMapper mapper, Func<RequisitionLineEntity, LineItem> lineItemFn);
    public static OrderMapper WithStatusFn(this OrderMapper mapper, Func<short, Status> statusFn);
    public static OrderMapper WithTransactionFn(this OrderMapper mapper, Func<IEnumerable<TransactionEntity>, Transaction> transactionFn);
    public static OrderMapper WithUserFn(this OrderMapper mapper, Func<string, User> userFn);
}

public class OrderMapper : TimestampMapper, IMapper<RequisitionEntity, Order>
{
    public Func<int, Account> AccountFn;
    public Func<AccountCustomerEntity, Address> AddressFn;
    public Func<RequisitionDeliveryDetailEntity, Article> ArticleFn;
    public Func<int, Carrier> CarrierFn;
    public Func<RequisitionLineEntity, LineItem> LineItemFn;
    public Func<short, Status> StatusFn;
    public Func<IEnumerable<TransactionEntity>, Transaction> TransactionFn;

    public OrderMapper();

    public void Map(RequisitionEntity requisitionEntity, Order order);
}

有人能帮我吗？
