我不断收到回复 -

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll

附加信息:执行超时已过期。操作完成前超时时间已过或服务器未响应。

附加信息:在模型生成期间检测到一个或多个验证错误:

Answer 1

在您的 connectionString 中添加 Connect Timeout=90。

connectionString="Data Source=k2mmbsouh0.database.windows.net;
        Initial Catalog=VoteWithDEV;Persist Security Info=True;User ID=username;Password=password;Connect Timeout=90 "
