我正在使用WCF数据服务(Odata)与.NET framework 4.5.1和EF 6.1.我已经使用代码第一种方法来创建EF模型.当我将此EF模型(AddProjectModel.cs)引用到WCF OData服务(WcfDataService1.svc)时,它会抛出以下错误:

错误:

服务器遇到处理请求的错误.异常消息是'在数据上下文类型'AddProjectModel',有一个顶级IQueryable属性'Assets',其元素类型不是实体类型.确保IQueryable属性是实体类型,或者在数据上下文类型上指定IgnoreProperties属性以忽略此属性.请参阅服务器日志以获取更多详 异常堆栈跟踪是:

这是我的WCF数据服务:WcfDataService1.svc

namespace AddProjectService
{
 public class WcfDataService1 : DataService<AddProjectModel>
 {
    // This method is called only once to initialize service-wide policies.
    public static void InitializeService(DataServiceConfiguration config)
    {
        // TODO: set rules to indicate which entity sets and service operations are visible,
         updatable, etc.
        // Examples:
        config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
        config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
        config.DataServiceBehavior.MaxProtocolVersion …
