Iâve been getting my slides and code samples together over the past few weeks for the upcoming conferences. The next one Iâll be at is at the end of this month in Boston at VSLive talking about transactions. The session is titled Lightweight Promotable Transactions using System Transactions and ADO.NET 2 and is at 2pm on June 30th. Below is the synopsis of the session and the agenda from my slide deck ⦠please drop by and say hi if you are attending.
The.NET Framework v2 includes the System.Transactions namespace that enhances transactional support for managed code. We'll discuss how System.Transactions can handle transactions without using other common practices such as deriving from a ServicedComponent, using interception, or using reflection. Designed to integrate with SQL Server 2005, System.Transactions supports the intelligent and automatic promotion of local lightweight transactions to fully distributed transactions. It also introduces a new class called LightweightTransactionManager, which is a faster alternative to using the DTC for local transactions. We'll walk through examples that modify the default transactional settings of the implicit local transaction and modify the isolation level, timeout period, and transaction's context, and more.
Agenda:
Transactional Support
Why use System.Transactions
Resource Managers
Ambient Transactions
Lightweight Transaction Manager (LTM)
Lightweight Transactions
Promoting them
How and when (and when not)
Implicit Transactions
Implicit because of default connection string setting of enlist=true
