The Evolution of C#
•

C/Win32
– Ugly syntax, notobject-oriented
– Manual Memory Management

•

C++/MFC
– Object-oriented layer for C

•

Visual Basic (through Version 6)
– Object “aware”, not object-oriented
– No multi-threading

•

Java
– Object-oriented
– Platform independence
– Cross-language integration limited

•

COM
– Reusable binary code
– Location transparency
– Deployment issues
– DLL Hell

• Windows Distributed Internet Architecture (DNA)
– Web development and deployment
– Too many technologies required (ASP, HTML, XML, JavaScript,
COM+)

• NET
–
–
–
–
–
–

Interoperability
Language Integration
Common engine for all languages
Less complex base class library
COM "issues" removed
Simplified deployment

• C#
– Leverages the power of .NETand OO development with a
"simpler" C-style syntax

Benefits of C#
• C# preserves C++ heritage
– Structured exception handling
– Similar statements, expressions & operators

• Improvements to C++
–

Benefits of C#
• Additional Language Features
–
–
–
–COM interoperability
Built-in code trust security
Metadata extensibility
XML support

• C# provides natural constructs to access .NET
framework functionality
• Brings a truly component-oriented language to
the C/C++ family
