你看这个吗？ http://stackoverflow.com/questions/35663759/asp-net-5-an-error-occurred-while-starting-the-application/35712042#35712042 –

我不知道，但我想不是，我发布在Windows Server上16，并更改我的连接字符串后得到此错误。 –

这不是解决方案，而是根据该答案查看实际错误。 “启动应用程序时发生错误”非常通用，可以让任何人真正洞察解决您的问题。 –

我不知道，如果你仍然需要回答这个问题。我有这个问题，我通过改变我的连接字符串来解决它。添加双反斜杠

{ "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Warning" } }, "ConnectionStrings": { "EstudantesCV21Context": "Server=myserver\\SQLEXPRESS;Database=mydatabase;userid=myid;password=mypass" } }
