推荐答案

亲爱的Shivam，



我在工作时面临同样的问题 WCF RIA服务教程，用于 LightSwitch 应用程序。它不是您需要引用的程序集。 ApplicationData 是LightSwitch自动创建的类，用于与 LightSwitch 的 Intrinsic 数据库进行通信（ LightSwitch 在\Bin\Data\Temp \ ApplicationDatabase.mdf）中创建一个LocalDB开发数据库。

所以你需要添加这个 ApplicationData WCF RIA服务项目的课程，以便与 LightSwitch 数据库进行通信。

要做到这一点，您需要右键单击 WCF RIA服务项目，然后选择添加，然后现有项目。

导航到.. .'YourLightSwitchProject'\ Server \GeneratedArtifacts 并单击 ApplicationData.cs 和添加为链接。

建议使用添加为链接，以便每当 LightSwitch 更新此类时， WCF RIA服务也会更新。

尽快您添加 ApplicationData.cs 类作为 WCF RIA服务的链接 使用ApplicationData.Implementation 所面临的问题将会解决。



最好的问候，

Dear Shivam,

I have faced the same problem while I was working on a tutorial for WCF RIA Services for a LightSwitch application. It is not an assembly that you need to reference. ApplicationData is a class that LightSwitch automatically creates, in order to communicate with the Intrinsic database of LightSwitch (LightSwitch creates a LocalDB development database in the location \Bin\Data\Temp\ApplicationDatabase.mdf).
So you need to add this ApplicationData class to your WCF RIA Service project to communicate with the LightSwitch database.
To do that you need to Right-click on your WCF RIA Service project and select Add then Existing Item.
Navigate to ...'YourLightSwitchProject'\Server\GeneratedArtifacts and click on ApplicationData.cs and Add As Link.
It is recommended to use "Add As Link" so that whenever LightSwitch updates this class, WCF RIA Service is also updated.
As soon as you add ApplicationData.cs class as a link to your WCF RIA Service the problem you face with using ApplicationData.Implementation will be solved.
