ADO.NET Express is an add-in for Visual Studio 2003 that generates class methods for calling stored procedures and executing common types of SQL statements. It supports C#/VB and SQL server/Oracle. ADO.NET Express looks similar to server explorer. You can add database connections and browse schema objects such as tables and stored procedures. You can right click on a schema object to generate ADO.NET code for this object. For example, you can right-click on a stored procedure and generate a C# method that executes the stored procedure and returns a DataReader.
ADO.NET Express is especially useful for ASP.NET and middleware developers who write a lot of data access code and would like to save time to do more creative tasks. Generated code can be modified. ADO.NET Express has a variety of options for generating code that cover most of the common data access scenarios. Generated code can also be used as a template for modification.
