Question

我尝试使用vscode在ubuntu上运行aspnet核心应用程序。当运行应用程序时，它会给我这个错误：

  System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnectionPool pool, DbConnection owningObject, DbConnectionOptions options, DbConnectionPoolKey poolKey, DbConnectionOptions userOptions)
   at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnection owningObject, DbConnectionOptions userOptions, DbConnectionInternal oldConnection)

ClientConnectionId:d48c3450-07f9-4cac-bc5f-97e7f7efa54a

但我没有使用集成身份验证，我的连接字符串如下所示："DefaultConnection": "Data Source=localhost;Initial Catalog=School360Db;User Id=[user];Password=[password];Trusted_Connection=True;MultipleActiveResultSets=true"

我在Windows上测试它，它可以工作！。

有什么想法吗？

Answer 1

如@jcmordan在评论中所述 - 设置Trusted_Connection = False。

Answer 2

我有类似的问题。

我正在使用Linux OS和Rider IDE，

我通过更改appsettings.json中的连接字符串来解决它：

"ConnectionStrings": {
"DefaultConnection": "Server=localhost;Database=ExampleDB;User=SA;Password=mypassword;ConnectRetryCount=0;MultipleActiveResultSets=true"

}

尝试这种格式，希望对您有所帮助。
