Visual Studio 2015 RC实体框架6.1.3迁移错误 [英] Visual Studio 2015 RC Entity Framework 6.1.3 Migrations Error

问题描述

仅当解决方案具有多个引用EntityFramework的项目时，才会发生粘贴以下错误。
当运行启用迁移或添加迁移时，我收到以下错误：

复制这个修补版本的EntityFramework.psm1 。

The pasted below error only occurs when the solution has more than one project that references the EntityFramework. When run the "Enable-Migrations" or "Add-Migration", I received the following error:

Output with EntityFramework 6.1.1:

Exception calling "LoadFrom" with "1" argument(s): "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters."

Copy this patched version of EntityFramework.psm1.
