使用“ TransactionScope”时，应该在Web服务器或数据库服务器中启用MSDTC吗？

Question

My question is related to this topic TransactonScope . I have a web server and a database server and a remote database server. I want to have a distributed transaction between local and remote server. I configured MSDTC for database servers and I can have a distributed transaction in Database servers with linked server. but when I use Transaction scope in system.transactions name space I encounter following error when I Just open the second connection (Remote Connection).

error:
  The transaction has already been implicitly or explicitly committed or aborted.

simplified code:

using (TransactionScope tscope = new TransactionScope(TransactionScopeOption.RequiresNew))
{
    //open connection db 1
    //insert into db1

    //open connection db2 (Remote databse) -- the problem is here
    //insert into db2

    tscope.Complete();
}

Answer 1

您应该启用它，因为运行时“必要时”会将事务升级为使用分布式事务处理协调器
