如何使用POCO实体发生器

问题描述

我用VS2010，我已经下载的并安装它，现在我想用它。

I'm using VS2010, and I've download the C# POCO Entity Generator and installed it, now I want to use it.

我无法读取 toturial 我找不到任何其他的好toturials，所以我了个去自己 - 我创建了一个模型，然后我创造新的POCO实体，但我得到了波纹管的错误：

I can't read the toturial and I can't find any other good toturials, so I've had a go myself - I have created a model and then I'm creating new POCO Entity, but I got the bellow error:

Error 1 Running transformation: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Unable to locate file

这是什么问题？我认为它无法找到模型映射，如果是这样的话，我该如何解决呢？

What is the problem? I think it can't find the model mapping, if this is the case, how do I resolve this?

推荐答案

检查this文章错误的描述，以及如何处理它。从Visual Studio中添加项目创建POCO模板时，它是路径替换的问题。

Check this article for error description and how to deal with it. It is problem of path substitution when creating POCO template from Add item in Visual Studio.
