    <p>I would like to configure WCF service operations to accept a transaction if my client sends one, but not to create one if none is sent. I think this would be similar to the Supported transaction attribute in COM+. </p> <p>Does anyone know whether this can be accomplished with WCF transactions?</p> <p>I am trying to accomplish this all by using the WCF transaction programming model (e.g. TransactionFlowAttribute and TransactionScopeRequired on service operations) rather than using the System.Transactions explicit transaction programming model. </p> <p>Here's an example of why I think I want to be able to do this:</p> <p>ServiceA implements a high-level business operation which invokes two data services. An operation in Service B does a single database update and an operation in Service C does two database updates. </p> <p>ServiceA ----> ServiceB ----> &lt;1 DB update><br> |<br> V Service C ----> &lt;2 DB updates> </p> <p>ServiceC's 2 database updates need to be performed within a transaction with its root on ServiceC. Service B's single database update does NOT need to take place within a transaction. However, ServiceA defines a transaction that requires ServiceB and ServiceC's database updates two happen as an atomic unit of work. </p> <p>My question is how I can configure ServiceB so that when it's invoked by ServiceA it enlists in that transaction. However, when ServiceB is invoked directly rather than through Service A it does not need to run within a transaction because it's only doing one database update. </p> <p>Thanks,</p> <p>David Madrian</p>

    1. COI posted the same question on MSDN and received some additional answers there that are interesting. Here's the link: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/7d3541b2-2c23-4a25-91a8-4a889c4d08be/ I'd be curious to hear what anyone thinks about the responses on MSDN.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
