VB Entity Framework Samples Now Available (Lisa Feigenbaum)
There are a lot of great Entity Framework samples on Code Gallery that you can now find available in Visual Basic .NET. This was recently announced on the ADO.NET team blog. Browse through the list below and start downloading!
ADO.NET Entity Framework Query Samples is a small Windows Forms program which contains several basic Entity SQL and LINQ to Entities queries against that NorthwindEF Entity Data Model (a modified version of Northwind). Its goal is to help you learn the features of the different query languages available in the Entity Framework, and to let you visualize how the results and the translated store queries look like.
This sample shows how to use code generation to add support for transparent lazy loading to Entity Framework. It includes code generator (EFLazyClassGen), supporting library (Microsoft.Data.EFLazyLoading) and sample test applications. EFLazyClassGen generates VB code that can be used instead of object layer generated by EdmGen or Entity Framework Designer. Generated code adds support for lazy entity objects that store their data in the form of flyweight objects. Object data is initialized on first access or navigation which means objects can exist without having non-key data loaded. http://blogs.msdn.com/jkowalski/archive/tags/EFLazyLoading/default.aspx has a series of articles that describe the library and its usage.
EF POCO Adapter enables Plain Old CLR Objects (POCOs) to be tracked using released version of Entity Framework V1. It consist of a code generator, supporting library and a test suite and examples. Entity Framework V1 programming interfaces are wrapped with corresponding APIs that work with POCO objects and do necessary translation between POCO and Persistence-Aware objects. See this blog post for more information about the project and its usage.
Description: The ADO.NET Entity Framework samples that accompany the Entity Framework documentation on MSDN. This is the download location for the CourseManager project that you create when you complete the Entity Framework quickstart. You will also find other Entity Data Model tools walkthrough projects as well as the samples described in the Entity Framework documenation.
Sample implementation of ADO.NET Data Services IUpdateable interface for Linq to Sql Data Sources. The easiest way to use this is to define a partial class for your DataContext type and provide the implementation there.
The ADO.NET Entity Framework Extensions library includes utilities that make querying stored procedures, creating typed results from DB data readers and state tracking external data much easier in the Entity Framework. A sample application demonstrates several patterns using these utilities, including stored procedures with multiple result sets, materialization of CLR types, and registering entities in the Entity Framework state manager.
