  • 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”.

  • 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.

  • Real-World MVVM with Entity Framework and ASP.NET Web API
    'I just completed a sample application using Simple MVVM Toolkit together with Trackable Entities to build a real-world N-Tier solution with a WPF client and portable POCO entities that are automatically change-tracked and sent to an ASP.NET Web API service that uses Entity Framework to perform asynchronous CRUD operations (Create, Retrieve, Update, Delete). Download the Simple MVVM Trackable Entities sample application here. View models have methods which call GetChanges on the change tracker, so that only changed entities are sent to the service.

  • Entity Framework - Model First: One-to-One relationship
    If you’re doing Model First with Entity Framework you may run into a scenario where you want to design a 1-to-1 relationship, but also have a foreign key be available on your entity. The default behavior in Entity Framework when doing a 1-to-1 relationship (with Model First), or 1-to-0.1 Add the entity that goes on the 1 side of the association, give it a primary key of type integer. Add the entity that goes on the 0.1 Click on the 1 entity and add an association, make it a 1-to-0.1, Entity Framework LINQ

  • Entity Framework – Model First: Generating DDL for Complex Types
    The complex type consists of 4 ‘fields’: CountryCode, AreaCode, Number and Extension: Each ‘field’ has properties set: The great part is that this is fully supported by the DDL generator, so right click on the Entity Framework Designer in Visual Studio 2010 and choose ‘Generate Database From Model…’ and the ‘Artist’ table will be generated as: -- --. -- Entity Designer DDL Script for SQL Server 2005, 2008, and Azure. -- --. -- --. -- Creating all tables. -- --. -- Creating table 'Artists'. CREATE TABLE [dbo].[Artists] Artists] (. ALTER TABLE [dbo].[Artists]. Artists].
