1, the list content is only in "when the list" only have the entrance, in fact, if the product details on the left side of the recommendation bar can be placed when the content of the list, to facilitate the user decision is still very helpful.

This sample application will contain a asp.net Web application that provides a read-only view of the blog post, and a Silverlight blog Administrator Client that allows the blog owner to edit articles.

Objectives of the Ado.net Entity framework
The conceptual model is abstracted from the complicated and miscellaneous relational data model. This allows developers to focus on the conceptual model without having to worry about the numerous and miscellaneous relational data models to improve development efficiency.
So how can this be done?The answer is: language-integrated Query and the Ado.net Entity Framework, the ado.net of the next generation.
The Ado.net Entity framework includes

This article focuses on programming data and how to eliminate the impedance mismatch between application and data services, such as reporting, analysis, replication services provided as part of SQL Server products, by raising the level of abstraction from the logical (relational) level to the concept (ent
The Microsoft. NET developer was able to create a OData source long before the OData specification appeared. WCF Data Services enables you to expose an Entity Data Model (EDM) on the Web using a representational state transfer (REST). In other words, these services can be used via the following HTTP calls: Get, put, DELETE, and so on. As the framework for creating these services evolves (changing names several times), the output is evolving and eventu
