SOA Data Access: Flexible Data Access With LINQ To SQL And The Entity Framework


Building a data access layer using LINQ to SQL and the ADO.NET Entity Framework allows you to decouple your application from the persistence technology you're using.

VS 2010: no Entity Framework or LINQ support for SQL Server 2000 SQLOLEDB connection?

Hello, I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider."If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?  

Asynchronous WCF call seems to be blocking

Hi all,I have a Silverlight application that calls a WCF web service which is hosted in an ASP.NET web application. On the client side I call two methods A and B on the service's interface asynchronously; each time a new proxy is created and used to call the respective method. Since the service has its InstanceContextMode set to PerCall, each call should create a new service instance and be independent from the others.For testing purposes I have added a Thread.Sleep(5000) to the implementation of method A.What I expect now is that when the client calls methods A and B one after the other, the service should process both calls in parallel and since method A has the call to Sleep(), method B should return first. Five seconds after that, method A should return as well.For the very first attempt in the web application's lifetime this works as expected, i.e. after rebuilding or performing an iisreset and calling those methods from the client side, it shows the expected behavior explained above. Here's a sample debug dump I received on the client:    Method B, 17:41:23, Server-Thread-ID: 9    Method A, 17:41:28, Server-Thread-ID: 8But after that, when I call those methods again (in exactly the same way), method A seems to block on the server:    Method A, 17:42:43, Server-Thread-ID: 1    Method B, 17:42:44, Serv

How to setup Query Result Shaping for LinQ to SQL instead of Entity Framework?

Hi, I am new to this, and I am trying to implement a linq query similar to db.Genres.Include("Albums") command from mvc music store using my current DB setup. I realize that the tutorial mentions Checlking the "Include foreign key columns in the method" when creating the tables in ADO.NET, but if I am using LINQ to SQL classes, then how can I obtain the same effect. And how do I use db.Genres.Include("Albums") to simplify my life? Thanks

Cancel asynchronous WCF call ?

In .NET 3.5, is it possible to cancel an asynchronous call to a WCF service ?   The desire is that a user search screen may fire a very long running SQL query in the middle tier, which they then want to cancel. The idea is that the actual database query gets cancelled, not just the WCF call to the middle-tier (otherwise the SQL query is still chewing up resources in the database). Is this possible ?   I'm using the event-based asynchronous pattern that was introduced for WCF in .NET 3.5, which Microsoft are now recommending to be used: http://msdn2.microsoft.com/en-us/library/ms734701.aspx e.g. Code Snippet ... //hook up Completed handler, and call service asynchronously. Use Tab|Tab to auto-generated in VS client.SomeMethodCompleted += new EventHandler<SomeMethodCompletedEventArgs>(client_SomeMethodCompleted); client.SomeMethodAsync(myParam); ...   //Asynchronous result - display in UI. //Completed event handler gets called on UI thread it was created from. void client_SomeMethodCompleted(object sender, SomeMethodCompletedEventArgs e) { //Do something with e.Result; }     Thanks, Andy.

Entity Framework - how to join tables without LINQ and with only string?


Hi all,

I have a question about Entity Framework. Please answer if you know answer on this. I have such query :

    String queryRaw =
        "SELECT " +
        "p.ProductName AS ProductName " +
        "FROM ProductEntities.Products AS p " +
        "INNER JOIN CategoryEntities.Categories AS c " +
        "ON p.CategoryID = c.CategoryID ";
    ObjectQuery<DbDataRecord> query = new ObjectQuery<DbDataRecord>(queryRaw, entityContext);
    GridView1.DataSource = query;

Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i can NOT use :



The question is can I use something like this instead of using objects?

query.Join ("INNER JOIN CategoryEntities.Category ON p.CategoryID = c.CategoryID ");

Is there a way to query entity based on multiple filter criteria? WCF Data Services, Linq to Entiti


Instead of:

DW_CMSOPEN dwc = new DW_CMSOPEN(new Uri("http://acctdev02/WCFDataService/EmployeeService.svc"));

dwc.Credentials = System.Net.CredentialCache.DefaultCredentials;

var employees = from emp in dwc.Employees 
             where emp.DEPT == "123"
             select emp;

I'd like the linq query to resemble:

var employees = from emp in dwc.Employees
              where emp.DEPT // in {"123", "456", etc}
              select emp;
