C# Transactionscope引发异常此平台在打开连接对象时不支持分布式事务

TransactionScope引发异常我正在使用.net core 2.2

在本例中，我首先创建TransactioScop的作用域，然后为一个工作正常的数据库打开SQL事务，然后在第一个事务之后，我调用commit，它将提交SQL事务，然后我尝试为另一个数据库打开call事务，同时创建事务系统引发异常

作为 消息“此平台不支持分布式事务。”

试图删除SQL事务

.NET Core不支持分布式事务，因为它需要在每个平台上使用不同的事务管理器。它可能会在将来出现（“这是正在进行的问题”），但就目前而言，任何需要两个不同资源管理器的事务都会抛出此异常

相反，您可以协调单独的事务。让两个单独的事务完成它们的工作，然后将它们都提交。有可能第一个成功，第二个失败，但对于SQL Server来说，这种情况非常罕见。比如：

            _db1UOW.Begin(); //creating sql transaction
            await _db1UOW.IDenialDetailsRepositorydb1.InsertDenialDetails(denialsDetails);
            await _db1UOW.IRuleDetailsRepositorydb1.InsertRulesDetails(rulesDetails);

            _db2UOW.Begin(); //creating sql transaction 
            await _db2UOW.IRuleDetailsRepository.GetRulesDetails();
            await _db2UOW.IDenialDetailsRepository.InsertDenialDetails(denialsDetails);
            var data = await _db2UOW.IRuleDetailsRepository.InsertRulesDetails(rulesDetails);

            _db1UOW.Commit(); //commitng sql transaction
            try
            {
               _db2UOW.Commit(); //commitng sql transaction
            }
            catch (Exception ex)
            {
               LogError("Second transaction failed to commit after first one committed.  Administrators may need to fix stuff");
               throw;
            }

或者，如果两个数据库位于同一台服务器上，则可以使用具有单个SqlConnection的跨数据库查询来登记单个SQL server事务中的更改。

不要同时使用事务范围和

Begin/CommitTransaction

，除非您真的想创建分布式事务。之所以使用TransactionScope，是因为您不必使用显式的Begin/Commit调用TransactionScope仅在Windows上有效。不确定您使用的是什么操作系统。我使用的是windows 7和visual studio 2017 vs 15.9。我已尝试删除sql Transaction开放GitHub问题。

            _db1UOW.Begin(); //creating sql transaction
            await _db1UOW.IDenialDetailsRepositorydb1.InsertDenialDetails(denialsDetails);
            await _db1UOW.IRuleDetailsRepositorydb1.InsertRulesDetails(rulesDetails);

            _db2UOW.Begin(); //creating sql transaction 
            await _db2UOW.IRuleDetailsRepository.GetRulesDetails();
            await _db2UOW.IDenialDetailsRepository.InsertDenialDetails(denialsDetails);
            var data = await _db2UOW.IRuleDetailsRepository.InsertRulesDetails(rulesDetails);

            _db1UOW.Commit(); //commitng sql transaction
            try
            {
               _db2UOW.Commit(); //commitng sql transaction
            }
            catch (Exception ex)
            {
               LogError("Second transaction failed to commit after first one committed.  Administrators may need to fix stuff");
               throw;
            }
