9 Microsoft.NET A Platform for Software Developer

10 Goals of.net Uniform model for desktop and Web programming So far Desktop programming object-oriented compiled (C/C++, Fortran,...) extensive class libraries Web programming ASP (not object-oriented) interpreted (VBScript, Javascript, PHP,...) specialized libraries Under.NET Desktop and Web programming object-oriented (even ASP.NET) compiled (C#, C++, VB.NET, Fortran,...) uniform class library

11 Goals of.net Interoperability between programming languages So far - millions of lines of code in C++, Fortran, Visual Basic,... - very limited interoperability Under.NET - binary compatibility between more than 20 languges (C#, C++, VB.NET, Java, Eiffel, Fortran, Cobol, ML, Haskell, Pascal, Oberon, Perl, Python,...) class in VB.NET subclass in C# used in Eiffel Public Class A Public x As Integer Public Sub Foo()... End Class class B : A { public string s; public void Bar() {...} } class Client feature obj: B;... create obj; obj.bar;... end

12 Interoperability class in VB.NET subclass in C# used in Eiffel Public Class A Public x As Integer Public Sub Foo()... End Class class B : A { public string s; public void Bar() {...} } class Client feature obj: B;... create obj; obj.bar;... end

13 Goals of.net More quality and convenience - Security strong static typing run-time type checks (no more buffer overruns!) garbage collection CIL code verifier public key signatures of code role-based access rights code-based access rights - Side by Side Execution versioning end of "DLL hell" - Simpler Software Installation no more registry entries clean and simple de-installation

14 What is the.net Framework? A software platform for the desktop and the Web Unmanaged Applications Operating System (Windows, Linux, Unix,...)

15 What is the.net Framework? A software platform for the desktop and the Web Unmanaged Applications Managed Applications Class Library Common Language Runtime Operating System (Windows, Linux, Unix,...) Common Language Runtime interoperability, security, garbage collection, versioning,... Class Library GUI, collections, threads, networking, reflection, XML,...

16 What is the.net Framework? A new software platform for the desktop and the Web Unmanaged Applications Managed Applications Class Library Web Applications Web Forms Web Services ASP.NET Common Language Runtime Web Server (IIS) Operating System (Windows, Linux, Unix,...) ASP.NET, Web Forms Web Services Web GUI (object-oriented, event-based, browser-independent) distributed services over RPC (SOAP, HTTP) e.g. WPF, WCF, WWF, XNA, Robotics, Parallel Programming,

17 A framework and more... What is the.net Framework? Unmanaged Applications Managed Applications Class Library Web Applications Web Forms Web Services ASP.NET Common Language Runtime Web Server (IIS) Operating System (Windows, Linux, Unix,...).NET Framework + Tools (Visual Studio.NET, ildasm, gacutil,...) + Servers (SQL Server, BizTalk Server, ExchangeServer,...) + Services (My Service, Passport Service,...)

18 Open Standard ECMA and ISO Standard C# Language Specification Common Language Infrastructure ISO Standards ISO/IEC (C#), ISO/IEC (CLI) Shared Source Implementation: SSCLI Free available Reference Implementation Windows, FreeBSD and MacOS X

19 Microsoft.NET Framework VB C# C++ JScript J#... Common Language Specification XML Web services Web Forms Windows Forms Data and XML Base Class Library CLR CLI

20 Common Language Runtime Execution of Managed Code Source Code Compilation Language Compiler Code MSIL Metadata Native Code Execution JIT Compiler Before installation or the first time each method is called
