我遇到了同样的问题，我已经找到了解决方案.. ConnectionString 中存在问题，将其更改为:

connectionString="Data Source(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-WebApplication3-20160303101342.mdf;Initial Catalog=aspnet-WebApplication3-20160303101342;Integrated Security=True"

收件人:

  connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=YourDatabaseName;Data Source=YourServerName"

它会在没有任何其他更改的情况下工作
