为什么dataContextClass的名称会自动更改? [英] why the name of the dataContextClass change automatically?

问题描述

我收到此错误:
找不到类型或名称空间名称"HwMangementDataContext"(您是否缺少using指令或程序集引用?)

我只是将所有表格的主键设置为onInsert并将此属性添加到一列

DbType ="UniqueIdentifier NOT NULL"

i get this error:
The type or namespace name ''HwMangementDataContext'' could not be found (are you missing a using directive or an assembly reference?)

i just set the primary key of all tabel to onInsert and add this property to one column

DbType = "UniqueIdentifier NOT NULL"

推荐答案

如果手动添加引用后出现相同错误，请尝试以下解决方案:

在项目属性下检查每个项目的构建类型-我敢打赌一个或另一个将针对.NET XX-客户端配置文件进行构建.

对于不一致的版本，尤其是其中一个是Client Profile，而另一个不是，则它在设计时起作用，但在编译时失败.一个真正的陷阱.

对我来说，Visual Studio 2010中发生了一件很有趣的事情，它使项目看似随机地设置为Client Profile，有时是在我创建项目时，有时是在几天后.可能是我不小心点击了某些键盘快捷键.

If you are getting the same error after adding the reference manually, then try the below solution:

Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile.

With inconsistent versions, specifically with one being Client Profile and the other not, then it works at design time but fails at compile time. A real gotcha.

There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I''m accidentally hitting.
