ObjectContext而不是DbContext(ObjectContext instead of DbContext)

我对EntityFramewok完全陌生,但我必须在下周的截止日期前与我的朋友写一个项目。 他创建了数据访问层并与我共享代码。 使用ADO.NET实体数据模型后,我发现他的类中有错误。 看来他使用了我没有的Add()方法。 在快速搜索后,我发现他为Context生成的模板在DbContext和ObjectContext之后继承。 为什么会这样呢? 我们使用相同版本的EntityFramework。


I'm completely new to EntityFramewok but I have to write a project with my friend with deadline next week. He created Data Access Layer and shared code with me. After using ADO.NET Entity Data Model I found errors in his classes. It appeared that he used Add() method which I don't have. After quick search I found that his generated templated for Context inherits after DbContext and mine after ObjectContext. Why does it happen so? We are using the same version of EntityFramework.

最满意答案

看起来设备上运行的gdbserver处于错误状态。

尝试重新启动设备然后apportable just_debug

如果仍有问题,请在问题中添加Android设备和Android版本。


It looks like there is a gdbserver running on the device in a bad state.

Try rebooting the device and then apportable just_debug

If there are still issues, add the Android device and Android version to the question.
