启用迁移无效

Question

I'm trying to add asp.net identity to my Web API, I typed in the package manager console : 我试图在我的Web API中添加asp.net身份，这是我在package manager console输入的：

PM> Enable-Migrations

But I got this error: 但是我得到了这个错误：

Cannot determine a valid start-up project. 无法确定有效的启动项目。 Using project 'MySite.API' instead. 而是使用项目“ MySite.API”。 Your configuration file and working directory may not be set as expected. 您的配置文件和工作目录可能未按预期设置。 Use the -StartUpProjectName parameter to set one explicitly. 使用-StartUpProjectName参数可以显式设置一个。 Use the -Verbose switch for more information. 使用-Verbose开关以获取更多信息。

No context type was found in the assembly 'MySite.API'. 在程序集“ MySite.API”中找不到上下文类型。

I made sure that the Web API project is the default project and the one that is selected on the dropdown. 我确保Web API项目是默认项目，并且是在下拉列表中选择的项目。

this is my packages.Config : 这是我的packages.Config ：
