家伙。我学习一个开放源码的MVC项目。但建成后（通过）。我得到了运行时错误。

推荐答案

检查数据库项目中引用。
你应该有和的EntityFramework上市EntityFramework.SqlServer。
如果没有尝试卸载并重新安装EF的NuGet包，它为我工作。

Check the references in the database project. You should have EntityFramework and EntityFramework.SqlServer listed. If not try uninstalling and re-installing the EF nuget package, it worked for me.
