c# - EF Core 内部 .NET Framework 数据提供程序错误 3

Question

我在使用 EfCore 和 AspNetCore.Identity 的 Asp.Net Core 应用程序上间歇性地遇到“内部 .NET Framework 数据提供程序错误 3”。

这是堆栈跟踪：

System.InvalidOperationException：Microsoft 的 Microsoft.Data.ProviderBase.DbConnectionPool.PrepareConnection(DbConnection owningObject, DbConnectionInternal obj, Transaction transaction) 的 Microsoft.Data.ProviderBase.DbConnectionInternal.PostPop(Object newOwner) 的内部 .NET Framework 数据提供程序错误 3。 Microsoft.Data.ProviderBase.DbConnectionPool.TryGetConnection（DbConnection owningObject，TaskCompletionSource1 retry, DbConnectionOptions userOptions, DbConnectionInternal& connection) at Microsoft.Data.ProviderBase.DbConnectionFactory.TryGetConnection(DbConnection owningConnection, TaskCompletionSource在 Microsoft.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource 1 retry, DbConnectionOptions userOptions) at Microsoft.Data.ProviderBase.DbConnectionClosed.TryOpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource1 重试, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection) 重试, DbConnectionOptions userOptions) 在 Microsoft.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource 1 retry, SqlConnectionOverrides overrides) at Microsoft.Data.SqlClient.SqlConnection.OpenAsync(CancellationToken cancellationToken) --- End of stack trace from previous location --- at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.OpenInternalAsync(Boolean errorsExpected, CancellationToken cancellationToken) at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.OpenInternalAsync(Boolean errorsExpected, CancellationToken cancellationToken) at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.OpenAsync(CancellationToken cancellationToken, Boolean errorsExpected) at Microsoft.EntityFrameworkCore.Storage.RelationalCommand.ExecuteReaderAsync(RelationalCommandParameterObject parameterObject, CancellationToken cancellationToken) at Microsoft.EntityFrameworkCore.Query.Internal.SingleQueryingEnumerable1.

应用信息：

• Asp.Net 核心 5.0.4
• AspNetCore.Identity 5.0.4
• EfCore 5.0.4
• Azure SQL 数据库

有没有人遇到过这种间歇性错误？

预先感谢您的反馈
