实体数据模型设计器不会打开edmx文件 [英] Entity data model designer won't open the edmx file

问题描述

奇怪的是，几天前它运行良好.我在表中添加了新列，并打算通过设计器更新模型，现在它显示实体数据模型设计器无法显示您请求的文件.您可以使用XML编辑器来编辑模型."

关于新字段，没有什么特别值得注意的地方，它只是SQL Server 2008中的一个不可为空的位字段.

解决方案

已通过删除文件并重新生成文件来解决.

The strange thing is, it was working fine a few days ago. I added a new column to a table and was going to update the model through the designer and now it says "The Entity Data Model Designer is unable to display the file you requested. You can edit the model using the XML Editor."

There's nothing particularly noteworthy about the new field, it's just a non nullable bit field in SQL Server 2008.

解决方案

Fixed by deleting the file and regenerating it.
