Visual Studio.NET

Integrated Development EnvironmentVisual Basic.NET

Many language enhancements

Inheritance,Overloading, Free Threading

Visual C++

Integration with .NET Framework with managed extensions

(classes)C#

New development language

Based on C/C++ with Garbage Collection/Memory Management

JUMP (Java User Migration Path) to .NET (1/25/01)

Visual J++ has been removed from the Visual Studio suite.

http://msdn.microsoft.com/vstudio

ADO.NET

ADO.NET is the preferred data accessmethod in the .NET Framework

Better support for disconnected dataaccess

Specialized namespacesSystem.Data.SQL – Tuned for SQL Server

System.Data.ADO – OLEDB

PortableNative XML Support

Pantech Solutions



ADO.NET

ADOConnectionSimilar to Connection object in ADO

ADOCommand

Similar to Command object in ADO

ADODataSetCommandSomewhat like Recordsets for ADO.NET (DataSet)

Designed for stateless operations

ADODataReader

For streaming methods, similar to StreamSQLConnection, SQLCommand, andSQLDataSetCommand, SQLDataReader
