当您创建一个空项目。创建MVC项目时，这意味着当您创建新项目时选择mvc勾选框，它将生成包含身份框架的所有模板。那么你们要做的就是创建一个新的MVC项目，并将与身份框架相关的这些文件复制到你的项目中:)

This happens when you create a empty project. When you create a MVC project, that means when you select mvc tick box as you create the new project it will generate all the templates including the identity framework. So what you guys have to do is create a new MVC project and copy those files related to identity framework in to your project :)
