更新數據庫失敗，錯誤 0x80131904（未找到服務器）

Question

我的應用程序有連接字符串

  <connectionStrings>
    <add name="XXX" connectionString="Data Source=(LocalDb)\v14.0;Initial Catalog=XXX;Integrated Security=SSPI; MultipleActiveResultSets=true" providerName="System.Data.SqlClient" />
  </connectionStrings>

在庫 XXX.Data 中。 但是在PMC中啟動update-database命令時，顯示錯誤：

Target database is: 'XXX' (DataSource: .\SQLEXPRESS, Provider: System.Data.SqlClient, Origin: Convention).
System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
   at System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity, SqlConnectionString connectionOptions, SqlCredential credential, Object providerInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString userConnectionOptions, SessionData reconnectSessionData, DbConnectionPool pool, String accessToken, Boolean applyTransientFaultHandling)

它嘗試連接到.\\SQLEXPRESS而不是(LocalDb)\\v14.0;Initial Catalog=XXX ？ 為什么？

我在任何 dll 文件中都沒有任何其他連接字符串。

更新 1：我嘗試使用其他連接字符串，但也失敗了：

<connectionStrings>
    <add name="XXX" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=XXX;Integrated Security=SSPI; MultipleActiveResultSets=true" providerName="System.Data.SqlClient" />
  </connectionStrings>

Answer 1

1. 我不得不卸載包含 EF 的 xxx.web 項目，但它沒有連接字符串。

2. 在第 1 步之后，它適用於以下帶有 2 個參數的命令：

    update-database -ConnectionStringName "XXX" -ProjectName "XXXX.Data"
