Le futur proche de DotNet: Mono, VisualStudio 2008, C#3, ..NET3.5, Ironpython2.0, LINQ

Des nouvelles en provenance de:

• http://www.asp-php.net/tutorial/asp.net/linq-1.php ("Cette article est, je l’espère, le première d’une série que j’ai décidé de nommer « LINQ et vous ». Force est de constater que dans la lignée de mes articles précédent relatifs au .NET Framework 2.0 et Visual Studio 2005, nous avons toujours dans cette nouvelle version une convergence de plus en plus forte des langages et outils de développements associés…")
• http://www.asp-php.net/tutorial/asp.net/linq-2.php?page=1 ("L’objectif est toujours de nous amener pas à pas vers la finalité de l’évolution du .NET Framework en version 3.5. Poursuivons ainsi notre découverte du .NET Framework 3.5 et de son écosystème !")

Les principaux enseignements de ces billets:

• Les versions de Framework et de la CLR ne sont pas pas associés. Entre 2005 et 2008 c’est toujours la machine virtuelle CLR V2.0=="Vous pouvez ainsi faire évoluer aisément vos applications actuelles vers les nouvelles librairies du .NET Framework 3.0 ou 3.5"
• les nouveautés des langages viennent non pas de la modification de la CLR mais des demandes des développeurs pour le développement de LINQ
• "Les évolutions du .NET Framework de la version 2.0 à 3.5 peuvent être en quelque sorte considérées comme des ajouts de nouvelles librairies basées elles-mêmes sur le .NET Framework 2.0 et de ce fait la CLR 2.0.
• Les projets Visual Studio 2005 sont récupérables sans migration dans Visual Studio 2008.
• Visual Studio 2008 vous permet de sélectionner la version du .NET Framework que vous souhaitez cibler pour chaque projet mais plus encore de modifier cette cible à tout moment !

• Le framework .Net (http://en.wikipedia.org/wiki/Microsoft_.NET)
• La bibliothèque de base (http://en.wikipedia.org/wiki/Base_Class_Library, "The Base Class Library (BCL) is a standard library available to all languages using the .NET Framework. In order to make the programmer’s job easier, .NET includes the BCL in order to encapsulate a large number of common functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation. It is much larger in scope than standard libraries for most other languages, including C++, and would be comparable in scope to the standard libraries of Java")
• C#3 (http://en.wikipedia.org/wiki/CSharp#C.23_3.0_new_language_features, "C# 3.0 is the next version of the language as proposed by Microsoft. It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime")
• Ironpython ("http://en.wikipedia.org/wiki/IronPython , Ironpython is an implementation of the Python programming language, targeting .NET and Mono, created by Jim Hugunin. Version 1.0 was released on September 5, 2006. The current 1.1 version targets CPython 2.4.4 for compatibility. However, there are some differences between the Python reference implementation and IronPython.[1]. Release 2.0, currently in alpha state, targets CPython 2.5. IronPython 2.0 is built on top of the Dynamic Language Runtime which contains a Dynamic Type System and Dynamic Language Hosting Environment abstracted out of IronPython 1. The DLR runs on top of the core CLR that ships with Microsoft Silverlight. This means that IronPython can be used for client-side browser scripting with Silverlight.")
• DLR (http://en.wikipedia.org/wiki/Dynamic_Language_Runtime , "The Dynamic Language Runtime (DLR) from Microsoft is a set of services that run on top of the CLR and provides language services like:
• Dynamic type system
• Dynamic method dispatch
• Dynamic code generation
• Hosting API. It can be used to implement dynamic languages like PythonRuby on the .NET Framework. The DLR services are used in IronRuby, a .NET implementation of the Ruby language, IronLisp, a .NET implementation of the Lisp language, IronPython 2.0, dynamic Visual Basic .NET (VBx) and Managed JScript (ECMAScript 3.0)"

• LINQ (http://en.wikipedia.org/wiki/Language_Integrated_Query , "Language Integrated Query (LINQ), pronounced "link", is a Microsoftsyntax reminiscent of SQL to .NET Framework programming languages, initially to the Visual Basic .NETC# languages. Many of the concepts that LINQ has introduced were originally trialled in Microsoft’s Cω research project. LINQ defines project that adds a native querying and standard query operators that allow code written in LINQ-enabled languages to filter, enumerate, and create projections of several types of collections using the same syntax. Such collections may include arrays, enumerable classes, XML, datasets from relational databases, and third party data sources. The LINQ project uses features of version 2.0 of the .NET Framework, new LINQ-related assemblies, and extensions to the C# and Visual Basic .NET languages. Microsoft has distributed a preview release of LINQ, consisting of those libraries and compilers for C# 3.0 and Visual Basic 9. LINQ is planned for release with the ‘Orcas‘ version of Visual Studio 2008. [6] The release date for Visual Studio 2008 has been announced by Microsoft as February 27, 2008.")

• Mono (http://en.wikipedia.org/wiki/Mono_%28software%29, "Mono is a project led by Novell (formerly by Ximian) to create an Ecma standard compliant .NET compatible set of tools, including among others a C#compiler and a Common Language Runtime. Mono can be run on Linux, BSD, UNIX, Mac OS X, Solaris and Windows operating systemsAug 29, 2007). This version provides the core API of the .NET Framework as well as partial support for C# 2.0 and Visual Basic.NET. Support for the 2.0 APIs is partial at this point (core, ADO.NET and ASP.NET) but other components like Windows.Forms are not yet complete. Complete support for the .NET Framework 2.0, including the .NET 2.0 version of Windows.Forms, is planned for Mono 2.2, by the end of 2007.Implementation of .NET Framework 3.0 is under development under an experimental Mono subproject called Olive, but the availability of a Mono framework supporting .NET 3.0 is still not planned yet. An open source implementation of Silverlight called Moonlight is now underway. Parts of it are in the core of Mono, parts are implemented as part of the Olive components. As stated by Miguel de Icaza, Moonlight will ship as part of Mono 1.2.6 release)
