在内存数据库中工作? [英] Work from an in-memory database?

问题描述

我有一种情况，我想读取一个OData提要，该提要构造为包含各种类型的记录的事件日志，然后构建可以使用LightSwitch应用程序进行探索的日志事件的结构化表示.读取OData feed没问题，我可以为LightSwitch应用程序设计数据模型并创建实体.但是我很难让查询返回任何结果，大概是因为我没有将更改提交给数据服务.

I have a scenario where I want to read an OData feed that's structured as an event log containing records of various types, and then build a structured representation of the log events that can be explored with a LightSwitch application. Reading the OData feed is no problem, and I can design a data model for my LightSwitch app and create entities. But I'm having trouble getting queries to return any results, presumably because I haven't committed my changes to a data service.

是否有一种方法可以使LightSwitch对抗内存中的表示形式?还是在没有真正的数据库连接的情况下使我的查询正常工作的方法?

Is there a way to get LightSwitch to work against an in-memory representation? Or a way to get my queries to work without having a real database connection?

谢谢

推荐答案

使用

Use a WCF RIA Service

这是WCF RIA服务，专门用于在内存中":

This is a WCF RIA Service that is specifically "in memory":
