定义查询，“枚举没有产生任何结果” [英] DefiningQuery, "Enumeration yielded no results"

问题描述

大家好，我正在编写一个简单的LOB SilverLight应用程序，我正在使用EF和.Net Ria Services来访问我的数据。到目前为止，我发现这些技术非常强大和灵活但是...我已经定义了一个DefiningQuery元素，它在模型中是sufaced ok。但是它没有将任何数据返回给我的程序。我已经验证了查询在SQL Management Studio中工作，我已经编写了一个方法来填充我的Domain Class。希望我错过了一些非常简单的事情。任何帮助都会非常感激，因为我已经尝试了几天了。非常感谢，Jonny

Hi all, I'm writing a simple LOB SilverLight application and I'm using the EF and .Net Ria Services to access my data. So far I'm finding these technologies very powerful and flexible however... I have defined a DefiningQuery element and it is sufaced in the model ok. However it isn't returning any data to my program. I have verified that the query works in SQL Management Studio and I've written a method to populate it in my Domain Class. Hopefully I'm missing something very simple. Any help would be greatly appreciated as I've been trying to work this out for a couple of days now. Many thanks, Jonny
