- ADO.NET Data Services (Astoria Project)
- http://astoria.mslivelabs.com/ (« The new wave of web applications are built on technologies such as AJAX and Microsoft Silverlight that enable developers to build better, richer user experiences. These technologies bring a shift in how applications are organized, including a stronger separation of presentation from data. ADO.NET Data Services (also known as Project code name “Astoria”) consists of a combination of patterns and libraries that enables any data store to be exposed as a flexible data service, naturally integrating with the Web, that can be consumed by Web clients within a corporate network or across the Internet. ADO.NET Data Services uses URIs to point to pieces of data and simple, well-known formats to represent that data, such as JSON and ATOM/APP. This results in data being exposed to Web clients as a REST-style resource collection, addressable with URIs that agents can interact with using standard HTTP verbs such as GET, POST, or
DELETE. » Je rajoute un bémol à la dernière phrase qui est inexacte: DELETE n’est pas un verbe HTTP. Pour rappel voir le billet que j’avais écrit à propos de Django: The
methodof an HTML form is limited to GET and POST. PUT and DELETE are not allowed. This isn’t some failure of browser vendors to properly implement the specification either. The HTML specification only allows GET and POST as form actions. XHTML and even XForms 1.0 don’t change this. This means it’s impossible to build a fully RESTful client application inside a web browser. Consequently everyone tunnels everything through POST, and simply ignores PUT and DELETE)

The project is lead by George Moudry and so far has providers for PostgreSQL, Oracle and Mysql. George keeps a blog http://code2code.net/wordpress/ where you can track the development of DbLinq. Thanks to Bryan for pointing me out to this fantastic piece of code. Mono users on Linux will now be able to use LINQ with open source databases from C# (in addition to our in-memory and XML providers). Update: A nice blog entry talks about Parallel LINQ. A version of LINQ that can be used to parallelize operations across multiple CPUs:
IEnumerable data = …;
// Regular code:
var q = data.Where(x => p(x)).
Orderby(x => k(x)).Select(x => f(x));
foreach (var e in q) a(e);
// Parallelized version, add the « AsParallel » method:
var q = data.AsParallel().Where(x => p(x)).
Orderby(x => k(x)).Select(x => f(x))
See more details about the above in the Running Queries On Multi-Core Processors article.« )

The programming model provided is quite simple and utilizes the same LINQ model, the new assembly is called System.Concurrency.dll which is the library that contains the new interface called IParallelEnumerable<T>, also it adds an extension methods for all collections and arrays that implement old IEnumerable, the extension method is called AsParrallel<T> which converts any collection to a Parallel enabled collection of type IParallelEnumerable<T> »)

- Native Windows.Forms driver for MacOS X allows Winforms-based applications to run without an X server.
- Support for the ASP.NET AJAX APIs and controls.
- Support for FastCGI deployments: ASP.NET can now be deployed on a multitude of servers that implement the FastCGI protocol (lighttpd for example) in addition to Apache.
- Windows.Forms now supports the WebControl on Windows and Linux using Mozilla.
- Runtime will now consume much less memory for 2.0-based applications due to various optimizations in generics support as well as including many new performance improvements and an updated verifier and an implementation of CoreCLR security.
- C# compiler is quickly approaching full 3.0 support, most of the basics work right now (except support for System.Query.Expression AST generation).

- http://ironpython-urls.blogspot.com/2007/12/ironpython-studio-now-available.html ( » IronPython Studio is a free full IDE (Integrated Development Environment) for the Python programming language. It is based on the existing IronPython example that is included in the VS SDK. IronPython Studio is based on the Visual Studio 2008 Shell runtime (royalty free) and can be installed without requiring any version of Visual Studio. It is hosted on codeplex. Installer, source and screencast are available from the download page. The sources require Visual Studio 2008 (Team Edition apparently) and the SDK. NOTE: Some users (myself included) had trouble getting this working. The magic steps are:
- Download and install the Visual Studio X redistributable from: Visual Studio Extensibility
- After you run the Install for the MS VS 2008 Shell Isolated Mode Redistributable, you must then go to the folder (« C:\VS 2008 Shell Redist\Isolated Mode« ) and click on: « vsshellisolated_enu.exe » to actually install the redistributable runtime.
- Install IronPython Studio. Thanks to Tom Clark for the instructions. »)
