数据源和实体框架6.1.1出现问题 [英] Issue with data sources and entity framework 6.1.1
问题描述
大家好
我有一个Windows窗体应用程序,正在使用Visual Studio 2013中的实体框架进行开发.当我将实体上下文中的数据源添加到VS2013中的数据源窗口时,我无法进行拖放操作.将数据源放到我的表单上.
I have a windows form application that I'm developing using the Entity Framework in Visual studio 2013. When I add a data source from my entity context to the data sources window in VS2013 I and unable to drag & drop the data source onto my form.
如果我通过向表单添加绑定源控件来添加数据源并设置数据源属性,那么我只能导航到父实体.我无法绑定到任何子实体,即使我在绑定源控件上设置了数据源 手动输入代码.
If I add a data source by adding a binding source control to the form and set the data source property I can only navigate to the parent entity. I am unable to bind to any of the child entities, even if I set the data source on the binding source control manually in code.
如果我将linq更改为Sql上下文,则一切正常.
If I change to linq to Sql context everything work fine.
能否请您告诉我如何解决此问题
