如何使用poco实体生成器

Question

我正在使用VS2010,我已经下载了C#POCO实体生成器并安装了它,现在我想使用它.

我无法阅读完整的 ¹并且我找不到任何其他好的组合,所以我自己去了 - 我已经创建了一个模型然后我正在创建新的POCO实体,但是我得到了波纹管错误:

问题是什么？我认为它找不到模型映射,如果是这种情况,我该如何解决？

Answer 1

查看本文以获取错误说明以及如何处理它.从Visual Studio中的"添加项"创建POCO模板时,这是路径替换的问题.

Answer 2

当TT文件中EDMX文件的路径不正确时,会发生此错误.要解决此问题,请打开TT文件,然后使用EDMX文件的相对路径手动替换路径.

例如,改变这个:

string inputFile = @"Db.edmx";

这样的事情:

string inputFile = @"..\DataAccess\Db.edmx";
