The document provides an introduction to .NET, describing what it is, its core components like the .NET Framework and Common Language Runtime (CLR), advantages such as cross-language development and improved security, and popular languages for .NET development like C# and Visual Basic .NET. Key aspects of the .NET Framework are outlined, including namespaces for organizing classes, support for web standards, and ADO.NET for database access. Differences between C# and Visual Basic .NET are highlighted, such as syntax and intended uses as a rapid application development tool.

Intro dotnet
- 1. Introduction to .Net May 5, 2012
- 2. Agenda Introductions What is .Net? .Net Framework Advantages of .Net Advantages of CLR Visual Studio 2005 .Net Languages C# vs. VB.Net Resources
- 3. What is .Net? New programming methodology Multiple Languages (VB.Net, C#, J#, Cobol.Net, etc.) JIT Compiler Primary Parts: .Net Framework Common Language Runtime (CLR) RTM: 2002 (v1.0) 2003 (v1.1) 2005 (v2.0) 2007 (v3.0) 2009 (v3.5)
- 4. What is .Net? New programming methodology Multiple Languages (VB.Net, C#, J#, Cobol.Net, etc.) JIT Compiler Primary Parts: .Net Framework Common Language Runtime (CLR) RTM: 2002 (v1.0) 2003 (v1.1) 2005 (v2.0)
- 5. .Net Framework A set of approximately 3500 classes. Classes are divided into namespaces grouping similar classes. For organization, each class belongs to only one namespace. Most classes are lumped into a name space called System System.Data: DB access System.XML: reading/writing XML System.Windows.Forms: Forms manipulation System.Net: network communication.
- 6. .Net Framework Supports Web Standards HTML XML XSLT SOAP WSDL (Web Services) ADO.Net: ActiveX Data Objects ASP.Net: Active Server Pages ILDASM: A tool used to properly display IL in a human readable format. .Net Compact Framework (mobile devices)
- 7. Advantages of .Net Write once, run everywhere Multiple programming languages (20+) Coding Reduction Controls Template projects IIS/Cassini support Ease of Deployment Security Features Evidence-based security Code access security The verification process Role-based security Cryptography Application domains
- 8. Advantages of CLR JIT allows code to run in a protected environment as managed code. JIT allows the IL code to be hardware independent. CLR also allows for enforcement of code access security. Verification of type safety. Access to Metadata (enhanced Type Information)
- 9. Advantages of CLR Support for developer services (debugging) Interoperation between managed code and unmanaged code (COM, DLLs). Managed code environment Improved memory handling Improved “garbage collection”
- 10. Visual Studio 2005 IDE for .Net development Dotfuscator encryption tools Cassini (IIS) Application Testing Center Team Suite for project management Express versions (free) VB6 to VB.Net conversion wizard
- 11. .Net Programming Languages Visual Basic.Net 1. RPG 2. Component Pascal C# 3. Mercury APL 4. Scheme Fortran 5. Curriculum 6. Mondrian Pascal 7. SmallTalk C++ 8. Eiffel Haskell 9. Oberon 10. Standard ML Perl 11. Forth Java Language 12. Oz Python COBOL Microsoft JScript
- 12. C# vs. VB.Net Differences lie in: Syntax Object Oriented Features Visual Studio.Net IDE
- 13. C# vs. VB.Net C# VB.Net No Auto Case adjust Auto case adjust Requires “{, }, ;” No line Enforces programming terminators rules. Requires “Begin, Unsafe Blocks End” Documentation Still intended as Comments RAD tool. Operator Overloading Allows late binding
- 14. C# vs. VB.Net C# VB.Net class App Class App { static void Main(string [ ] args) Shared Sub Main(ByVal args { as String( ) ) int intCounter=0; Dim arg as String Dim intCounter as Integer foreach (string arg in args) { For Each arg in args System.Console.WriteLine(“ Counter:” + System.Console.Writeline(“ intCounter.ToString() + “=“ Counter: ” & intCounter & + arg); “=“ & arg) } //end of foreach Next ‘For Each loop } //end of Main() End Sub ‘end of Main()
- 15. Documentation Comments (C#) ///<summary> ///A Sample Function to demonstrate C# ///</summary> ///<param name=“void”>This function does not receive a parameter. </param> ///<returns>Void Type</returns> Void SampleProc() { int intCounter1, intCounter2; MessageBox.show(“Counter1=” & intCounter1); } //end of SampleProc
- 16. C#/VB.Net Myths VB.Net is intended for use with Microsoft Office. C# is the latest release of C++. C# is easier to learn than VB.Net. To learn C#, one should first learn C++. C# is more advanced than VB.Net C# runs faster than VB.Net
