In our last post, we looked into objectives of the ADO.NET 3.5 which get shipped with VS 2008 Service Pack1. To achieve those objectives, we have some very good language extensions for ADO.NET 3.5. in C# and VB.
- LINQ extension for VB 9.0 and C# 3.0 language provides a set of standard query operators to query many different kind of data sources using SQL like syntax. This extension for VB and C# implements LINQ pattern.
- LINQ to Object is the default implementation for LINQ. It enables the developer to execute queries against a data persisted in memory that implements IEnumerable or IQueryable interface.
- LINQ to SQL extension to LINQ to Objects provide an O/RM tool to generate and manage classes for business objects and to persist their instances in SQL Server tables.
- LinqDataSource server control introduced in ASP.NET 3.5 simplifies the headache to bind data enabled web controls to business objects created with LINQ to SQL.
Later on we will discuss each of the above mentioned extensions individually, to look under the hood of ADO.NET 3.5 and it’s working.
Until than happy reading
