Removing .NET ClickOnce Support from Firefox

Microsoft is really making it hard not to distrust them, aren't they? We already talked about Mono and Moonlight this weekend, and now we're notified of something else. Apparently, the Microsoft .NET Framework 3.5 Service Pack 1, released earlier this year, installs a Firefox extension which could not be uninstalled easily (registry hacking was needed). To make matters worse, this extension came with a pretty big security hole (at least, that's what everyone says). A newer version of this extension has been pushed out in May, which can be uninstalled the proper way. As it turns out, Firefox apparently has a limitation in that extensions installed at the machine level (instead of the user level) cannot be uninstalled from within the extensions GUI.

Microsoft Turns .Net Micro Code, Support Over to Community

"Microsoft is turning the source code for its embedded .Net Micro Framework over to the community and slowly withdrawing from that business, company officials are confirming. On the rumored list of teams most heavily impacted by second wave of Microsoft layoffs announced on May 5 was the .Net Micro Framework team - as well as the related MSN Direct unit. Indeed, both groups were affected, a Microsoft spokesperson confirmed on May 6."

Microsoft Releases ASP.NET MVC Source Under Open License

"Microsoft launched ASP.NET MVC 1.0 at the MIX09 event last month. This new ASP.NET enhancement brings a Rails-like model-view-controller framework to Microsoft's Web development stack. In a blog entry published on Wednesday, Microsoft developer division vice president Scott Guthrie announced that the framework is now open source. The source code is available under the terms of the Microsoft Public License (MS-PL), a permissive open source software license that has been approved by OSI and is characterized by GNU as a free software license. Microsoft's move to open the framework will enable third-party developers to modify the source code, incorporate it into their own software, and share it with other users."

Microsoft: No External Code in DLR

"It's official: Microsoft will not accept any external code contributions to its planned Dynamic Language Runtime, which will run Microsoft's new scripting languages for the web and Silverlight content on .NET. Microsoft will, though, continue to accept source-code contributions to its slowly emerging implementation of Ruby for .NET, IronRuby. Contributions are helping to build IronRuby and shepherd the language towards the first-full release. The Register has learned, meanwhile, that Microsoft will start accepting external contributions to its other great scripting language project, putting Python on .NET - IronPython - in the "near future". The promise by Microsoft IronRuby lead John Lam comes nearly a year after the topic was first raised. The reason Microsoft decided to leave the DLR closed, despite taking contributions to the languages that will run inside it, is to protect itself from unwanted licenses and IP claims."

Announcing Pash: Open Source Implementation of PowerShell

Igor Moochnick announced Pash, an open source implementation of Microsoft's PowerShell. "The main goal is to provide a rich shell environment for other operating systems as well as to provide a hostable scripting engine for rich applications. The user experience should be seamless for people who are used to Windows version of PowerShell. The scrips, cmdlets and providers should runs AS-IS (if they are not using Windows-specific functionality). The rich applications that host PowerShell should run on any other operating system AS-IS. Secondary goal: the scripts should run across the machines and different OS’s seamlesly (but following all the security guidelines)."

SharpOS in the Stream of C# Kernels

"Previously, we have presented one of the two opensource licensed projects related to creating a C# kernel. Now it's the time to complete the set by rightfully presenting SharpOS, an effort to build a GPL version 3 + runtime exception licensed system, around a C# kernel of their own design. It is my pleasure and priviledge to host a set of questions and answers from four active developers of SharpOS, that is William Lahti, Bruce Markham, Mircea - Cristian Racasan and Sander van Rossen in order to get some insight into what they are doing with SharpOS, their goals, their different design and inspiration."

Developers Create Open-Source OS Kernels Using .NET Tools

"Developers are working to create experimental open-source operating systems with modular microkernels using the C# programming language. The SharpOS and Cosmos projects both announced their first major milestone releases last month, demonstrating the technical viability of the concept. Although some previous research has been conducted in the area of VM-based operating systems, the Cosmos and SharpOS projects break a lot of new ground. One particularly notable prior effort in this field is Microsoft's Singularity experiment, a research project that that began in 2003 with the intent of creating a managed code operating system that uses the Barktok compiler and leverages static analysis and programmatic verifiability to ensure high dependability."

SharpOS Releases First Milestone

SharpOS 0.0.1 has been released. "The SharpOS project is aimed at writing an operating system in 100% C#. This originally proved to be a problem of nearly philosophical proportions because C# is a managed language, and by nature isn’t designed for such low-level uses as developing an operating system kernel. Please note that although our goal is to create an operating system in C#, the infrastructure we have created allows kernels to be written in any language that targets the Common Intermediate Language bytecodes and exposes pointers and unsafe code."

Parallel Computing with .NET

"With all the modern systems using multi-core and multi-processor systems, tapping this new power is an interesting challenge for developers. It also fundamentally starts the shift on how your 'average Joe' interacts with a computer and things that he/she expects to be able to. First, check out the 'Manycore Shift' paper from Microsoft. Second checkout the Parallel Extensions to .NET 3.5 which is a programing model for data and task parallelism. It also helps with coordination on parallel hardware (such as multi-core CPU's) via a common work schedules. There is also a new Parallel Computing Dev Center on MSDN. Before you download the December 2007 CTP, make sure you have the RTM bits of the .NET 3.5 runtime. There are also a number of bugs fixed in this new CTP. If you want a quick introduction then check out a few videos available."

Microsoft To Open Visual Studio Source Code to Top Partners

Microsoft announced two significant licensing changes around Visual Studio that will be a boon for partners. First, the company said it will soon initiate a shared-source licensing program for Visual Studio and make the IDE's source code available to ISV partners for debugging purposes. Microsoft also removed a licensing restriction that previously limited use of the Visual Studio software development kit to development only around Microsoft's platforms: partners will now be free to create Visual Studio-based applications and extensions on Linux and other non-Windows platforms.

MS To Release Source Code to .NET Framework Libraries

"One of the things my team has been working to enable has been the ability for .NET developers to download and browse the source code of the .NET Framework libraries, and to easily enable debugging support in them. Today I'm excited to announce that we'll be providing this with the .NET 3.5 and VS 2008 release later this year. We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries, ASP.NET, Windows Forms, ADO.NET, XML, and WPF. We'll then be adding more libraries in the months ahead (including WCF, Workflow, and LINQ). The source code will be released under the Microsoft Reference License."

The Evolution of LINQ and Its Impact on the Design of C#

"I was a huge fan of the Connections series, hosted by James Burke, when it aired on the Discovery Channel. Its basic premise: how seemingly unrelated discoveries influenced other discoveries, which ultimately led to some modern-day convenience. The moral, if you will, is that no advancement is made in isolation. Not surprisingly, the same is true for Language Integrated Query (LINQ). In simple terms, LINQ is a series of language extensions that supports data querying in a type-safe way; it will be released with the next version Visual Studio, code-named "Orcas." The data to be queried can take the form of XML (LINQ to XML), databases (LINQ-enabled ADO.NET, which includes LINQ to SQL, LINQ to Dataset and LINQ to Entities), objects (LINQ to Objects), and so on."

C# Callback and Event Mechanisms

All too often, source code spends a lot of time on basic housekeeping, monitoring the state of many objects. This is wasteful, and with C# it is unnecessary. Software expert Stephen Morris shows how C# provides a range of callback mechanisms that obviate the need for polling objects for state information.

Microsoft to Deliver Visual Studio 2005 Update for Vista

Microsoft said it will soon release a new version of its Visual Studio toolset for Windows Vista development. Jay Roxe, group product manager for Visual Studio, said Microsoft will introduce a new release of the Visual Studio targeting Vista development, known as Visual Studio 2005 Service Pack 1 Update for Windows Vista, as soon as March 5 but possibly as late as March 12 depending on when internal developers clear the code for general use.

First Look at Orcas

"One of the highlights of my recent trip to Europe was getting the chance to publicly show off some of the new features in our next release of Visual Studio and the .NET Framework (codenamed 'Orcas') for the first time publicly. You can download the deck I presented here . You can also watch a version of the Belgium talk. Orcas is going to be a pretty exciting release, and contains a ton of great functionality that I think you will really love. I'll be drilling down into more details of it over the next few months in many more blog posts."

Interactive 3D Controls on the Windows Presentation Foundation

Thanks to the efforts of Kurt Berglund, a new hire on the Windows Presentation Foundation (formerly "Avalon") team, there is now a library that allows standard WPF controls (like buttons, text boxes, lists) to be used interactively on 3D objects. This is not a native feature of the 1.0 version of the framework--such items could be displayed, but were non-interactive. See this channel9 video or this blog post for details on how this (dare I say) clever hack works. Source code is also available.
