C# NCache作为实体框架二级缓存未与数据库同步

使用NCache 4.6作为EF 6.1.3二级缓存时，SqlDependency不起作用。（它无法检测我直接在SQL server中所做的更改。在使用EF向数据库添加或删除实体时，也不会更新缓存或使其无效。尽管它检测到更新实体）

我已在我的计算机中安装了具有IP:

192.168.56.1的NCache，并在具有IP:
192.168.56.101的vbox中安装了SQL server 2014

使用来自的指令并自定义它们以满足我的IP和用户的要求，我执行了以下SQL：

ALTER DATABASE NORTHWND SET ENABLE_BROKER with rollback immediate;
GO
--Select is_broker_enabled from sys.databases where name ='NORTHWND'

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO user1
GRANT CREATE QUEUE TO user1
GRANT CREATE SERVICE TO user1
GRANT CREATE PROCEDURE TO user1


CREATE QUEUE "NCacheSQLQueue-192.168.56.1";
CREATE SERVICE "NCacheSQLService-192.168.56.1" ON QUEUE."NCacheSQLQueue-192.168.56.1"([http://schemas.microsoft.com/SQL/Notifications/PostQueryNotification]);

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO user1;
GRANT RECEIVE ON "NCacheSQLQueue-192.168.56.1" TO user1;
GRANT RECEIVE ON QueryNotificationErrorsQueue TO user1;
GRANT SEND ON SERVICE :: "NCacheSQLService-192.168.56.1" to user1;

ALTER DATABASE NORTHWND SET ENABLE_BROKER with rollback immediate;
GO

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO sa
GRANT CREATE QUEUE TO sa
GRANT CREATE SERVICE TO sa
GRANT CREATE PROCEDURE TO sa

ALTER AUTHORIZATION ON DATABASE::[NORTHWND] TO sa

另外，
select*from sys.dm_qn_subscriptions
显示没有人订阅。
结果表明，我需要对数据库运行
ALTER AUTHORIZATION:：[NORTHWND]to user1

以下是我所做的：

1-恢复了一个新的Northwind数据库

2-运行以下SQL：

ALTER DATABASE NORTHWND SET ENABLE_BROKER with rollback immediate;
GO
--Select is_broker_enabled from sys.databases where name ='NORTHWND'

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO user1
GRANT CREATE QUEUE TO user1
GRANT CREATE SERVICE TO user1
GRANT CREATE PROCEDURE TO user1


CREATE QUEUE "NCacheSQLQueue-192.168.56.1";
CREATE SERVICE "NCacheSQLService-192.168.56.1" ON QUEUE."NCacheSQLQueue-192.168.56.1"([http://schemas.microsoft.com/SQL/Notifications/PostQueryNotification]);

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO user1;
GRANT RECEIVE ON "NCacheSQLQueue-192.168.56.1" TO user1;
GRANT RECEIVE ON QueryNotificationErrorsQueue TO user1;
GRANT SEND ON SERVICE :: "NCacheSQLService-192.168.56.1" to user1;

ALTER DATABASE NORTHWND SET ENABLE_BROKER with rollback immediate;
GO

GRANT SUBSCRIBE QUERY NOTIFICATIONS TO sa
GRANT CREATE QUEUE TO sa
GRANT CREATE SERVICE TO sa
GRANT CREATE PROCEDURE TO sa

ALTER AUTHORIZATION ON DATABASE::[NORTHWND] TO sa

注意，在这个查询中，我故意省略了
创建队列“NCacheSQLQueue-192.168.56.1”和之后的所有查询

另外，我发现它与NCache或SQL依赖项都不兼容，所以我禁用了它
