entity-framework - 仅 EntityFramework 中的事务不匹配

Question

我有一个存储过程

CREATE PROCEDURE [dbo].[GetNextImageRequest]
(...) AS

DECLARE @ReturnValue BIT
SET @ReturnValue = 1

-- Set paranoid level isolation: only one access at a time!
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE 
BEGIN TRANSACTION

BEGIN TRY 
    ...
    UPDATE STATEMENT THAT THROWS FOREIGN KEY EXCEPTION           

    IF @@trancount > 0
    BEGIN
        COMMIT TRANSACTION
    END
    SET @ReturnValue = 0
END TRY

BEGIN CATCH
    IF @@trancount > 0
    BEGIN
        ROLLBACK TRANSACTION
    END
    SET @ReturnValue = 1
END CATCH 

SET TRANSACTION ISOLATION LEVEL READ COMMITTED
SET NOCOUNT ON

RETURN @ReturnValue   -- 0=success

GO

当我从 Sql Server Management studio 手动调用它时，我没有得到任何异常。 当我通过 Entity Framework 6 调用它时，我得到

Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 0.

我做错了什么？外键约束正在回滚，但我正在检查@@TRANCOUNT。

Entity Framework 6 (EF6) 在 ExecuteSqlCommand 之前添加这一行

db.Configuration.EnsureTransactionsForFunctionsAndCommands = false;
