    <p>You might find the article on code project useful in regards to this question <a href="http://www.codeproject.com/Articles/188749/WCF-Sessions-Brief-Introduction" rel="nofollow">Here</a></p> <p>Session is a well understood term for all of us and as per our common understanding, it is (well, less or more) some duration in which entities recognize each other. Some of us might have played with it in ASP.NET as well. The concept is almost similar in WCF although the technique and usage are a bit different.</p> <p>In WCF, there is always a service class instance that handles incoming service requests. These instances may already be there (at server when request arrives) or may be created as needed. In WCF, the concept of session is mainly to manage these service instances so that server can be utilized in an optimized way. At the server, there is one special class named InstanceContext that creates/loads service class instance and dispatches requests to it. The correlation can be perceived as:</p> <p>You can see here how stuff is engaged. When some request arrives, it is routed to service instance via instance context. Suppose there is a hit of thousand requests, then service will have to create thousand instance contexts (which in turn will create thousand service instances) to handle these requests. If requests are served in this way, then service is called PERCALL service as each request is served by a new instance context and service instance object (call them as service objects onwards). Consider there is a client that made 100 requests. If service identifies this client and always serves it by a dedicated service object, then this type of service will be known as PERSESSION service as it recognizes the client and serves it by a single instance of service object. On the other hand, if all the requests irrespective of client are served by a single instance of service objects, then the service will be known as SINGLETON service. The following pictures summarize the concept: THE LINK ABOVE WILL HAVE MORE INFO.</p>

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.
