在事务中使用异步方法报错A TransactionScope must be disposed on the same thread that it was created.

只需要将这个地方改一下就可以了哦

using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required))
{
    }

 using (TransactionScope ts = new TransactionScope(TransactionScopeAsyncFlowOption.Enabled)){
    }
