MigrationsSqlGeneratorDependencies(IRelationalCommandBuilderFactory, IUpdateSqlGenerator, ISqlGenerationHelper, IRelationalTypeMappingSource, ICurrentDbContext, IModificationCommandFactory, ILoggingOptions, IRelationalCommandDiagnosticsLogger, IDiagnosticsLogger<DbLoggerCategory.Migrations>)

這是支援 Entity Framework Core 基礎結構的內部 API，不受與公用 API 相同的相容性標準。 它可能會在任何版本中變更或移除，而不會有任何通知。 您應該只在程式碼中直接使用它，並知道這麼做可能會導致應用程式在更新至新的 Entity Framework Core 版本時失敗。

備註

請勿直接從提供者或應用程式程式碼呼叫此建構函式，因為它可能會在新增相依性時變更。 請改用建構函式中的這個類型，以便由相依性插入容器自動建立和插入實例。 若要建立已取代某些相依服務的實例，請先從相依性插入容器解析物件，然後使用 C# 'with' 運算子取代選取的服務。 請勿在此進程中的任何時間點呼叫建構函式。
