DevelopMentor Courses - Tuesday, February 28, 2012 | | The Best from Tony and Zuzana's World | MORE | | | | - Webinar: N-Tier Entity Framework with DTOs
I recently delivered a free webinar for DevelopMentor on n-tier application development using Entity Framework 4.0. In it I explained how to use what I call “Trackable Data Transfer Objects” to achieve the same result as “Self-Tracking Entities” but using a more lightweight tracking mechanism to achieve better interoperability, as I outlined in this blog post. The screencast video is now available to be streamed or downloaded. The slides and code for the presentation are also available. Tony and Zuzana's World - Wednesday, April 21, 2010 - Setting up SQL Server 2008 Express with Profiler
When I teach my DevelopMentor course on Entity Framework 4.0 and WCF Data Services , I use the Express Edition of SQL Server 2008 R2, but I have need for the SQL Profiler tool, which comes only with the full version and is needed to inspect what SQL is sent to the database. In addition, the setup folks often have a hard time getting the permissions right. So I wrote a script that first installs just the tools from a trial version of the Developer Edition, which include both SQL Management Studio and SQL Profiler. Click on the Eval X86 Executable link to download SQLFULL_x86_ENU.exe. Tony and Zuzana's World - Thursday, August 5, 2010 - Peeling Back the Onion Architecture
If, for example, the data access layer is represented by a number of repository interfaces, you can swap out LINQ to SQL with Entity Framework or NHibernate (or your favorite ORM) without breaking other parts of the application. This layer would contain your POCO entities. Surrounding your domain entities are repository interfaces, which are in turn surrounded by service interfaces. Download the code for this article. Writing applications that are testable requires that you separate business logic from presentation logic so that they can be independently tested. Tony and Zuzana's World - Saturday, October 8, 2011 - EF4 compared to NHibernate
Last week while teaching my new LINQ and Entity Framework course I got a question asking me to compare EF4 with NHibernate. EF is more than an ORM and supports a streaming model with data readers against the entity model without materializing entities. EF has an end-to-end n-tier solution out of the box with Self-Tracking Entities (nothing like that for NH). Not having worked extensively with NHibernate, I wasn’t in a position to address the question. EF supports LINQ out of the box (NH doesn’t have it yet). EF has a good designer (NH doesn’t).

The resulting XML is used to populate client-side entities, which are change-tracked. Scott Hanselman Interview with Pabro Castro on OData Open Data Protocol (OData) WCF Data Services Team Blog Entity Framework 4.0 Someone recently asked me this question: When a company that has been using 2 tiers wants to move to n-tier, what are the considerations for choosing WCF and STEs [or Trackable DTOs] vs. WCF Data Services? m going to steal an image from the.NET Endpoint blog , because it shows how each programming model rests on top of the infrastructure provided by WCF.

I’ll be presenting a free DevelopMentor web cast on Tuesday Dec 8, 2009 at 9:00 am (Pacific Standard Time) on new features in Entity Framework 4.0. The web cast includes slides and demos , as well as question-and-answer periods in which we’ll discuss some of the other new features coming in Entity Framework 4.0.

Kennedy's Weblog - Monday, May 6, 2013 Optimistic concurrency in MongoDB using.NET and C# That may be fine for bank transfers, but it typically falls down in the face of disconnected models used by almost all ORMs such as Entity Framework. Frameworks such as Entity Framework have optimistic concurrency control built in (although it may be turned off). Basically there are three steps: Get an entity from the DB and disconnect. The only thing you need to do to use this library in your apps is to implement this interface on all top-level MongoDB entities and use a class derived from ConcurrentDataContext (in library below) for your data access.

| The Best from DevelopMentor | MORE | - Entity Framework 5 + Enumerations => What’s not to love?
Entity Framework 5 now supports enumerations (when using Visual Studio 2012 and targeting the.NET 4.5 framework). Next we’ll generate an entity data model from the database. Using enumerations with Entity Framework 5. We need to change the type of the ‘Habitable’ column in the database to a tinyint and we need to modify the information in the conceptual schema to inform the entity framework of our change in design: The screenshot shows that we need to change the underlying type as well as check the “Set Flags attribute”. DevelopMentor Courses - Sunday, September 2, 2012 - Entity Framework 5 is available
Entity Framework 5 is included in Visual Studio 2012, but is also available to users of Visual Studio 2010 (as a NuGet package: [link] ). Note: Some Entity Framework 5 features are only available when writing an application that targets.NET 4.5. Entity FrameworkThis includes enum support, spatial data types, table-valued functions and the performance improvements. Read more about what is new on the MSDN ADO.NET blog: [link]. DevelopMentor Courses - Sunday, August 26, 2012 - Reporting using Entity Framework
Technologies like Entity Framework help us convert data in the database to.NET objects and add logic. 39: Next step is to create a WCF service application, add an Entity Framework model and drag the two views onto the model: Next we’ll implement two methods to use the Entity Framework model to select the data and return a list of CustomerView or OrderView objects. For many years the mantra for implementing business logic in your line of business application has been: “don’t put it in the database, don’t put it in the user interface”. Life is good.

If you’re using Entity Framework Code First, then you may want to create an index on some of your table. Entity FrameworkThe way to do this is to call “Database.ExecuteSqlCommand” in the “Seed” method of your database initializer. The sample below shows how it is done (thanks to Rolf for pointing me in the right direction): using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Entity; using System.ComponentModel.DataAnnotations; namespace CodeFirstPlayground. {. class Program. {. static void Main( string [] args ). {.
