New Windows 8, new Visual Studio 2012

Microsoft has released the Release Candidate of Visual Studio 2012 (now the official name), which you can download here, to coincide with the release of Windows 8 Release Preview and Windows Server 2012 Release Preview.

Visual Studio also has a new logo, as you can see from the setup window below.

Convert .NET Intermediate Language to JavaScript

Whomever called JavaScript the assembly language of the web was a true prophet.

Compiling .Net code to JavaScript is not new. I have heard that Microsoft’s Office Web Apps, browser-hosted editing of Office documents, are built with Script#.

The difference with JSIL is that it compiles .NET Intermediate Language (IL), and therefore works with

A simple example of async and await in C# 5

I have been playing with the Visual Studio 11 developer preview and exploring its asynchronous features, specifically the async and await keywords which are new to C# 5.0. These features have actually been available as a CTP (Community Tech Preview) since October 2010, but I had not found time to try it.

I like to

Reflections on Microsoft BUILD 2011

I’m just back from Microsoft’s BUILD conference at Anaheim in California, which lived up to the hype as a key moment of transition for the company. Some said it was the most significant PDC – yes, it was really the Professional Developers Conference renamed – since 2000, when .NET was introduced; some said the most

A few facts about Microsoft’s new Windows Runtime

I’ve just come out of Martyn Lovell’s talk on WinRT internals here at BUILD in Anaheim, California.

Make no mistake: Microsoft has re-invented the Windows API in WinRT. Just to recap, WinRT is the API for Metro-style applications, the touch-centric, app-centric API for tablets and, one presumes, eventually for Windows Phone (though Microsoft has yet

The strategy behind Mono has shifted: ten years of open source .NET

Yesterday, SUSE and Xamarin announced, in effect, the transfer of all things Mono to Xamarin.

The agreement grants Xamarin a broad, perpetual license to all intellectual property covering Mono, MonoTouch, Mono for Android and Mono Tools for Visual Studio. Xamarin will also provide technical support to SUSE customers using Mono-based products, and assume stewardship of

C# vs C++ and .NET vs Mono vs Compact Framework performance tests

A detailed benchmark posted on codeproject investigates the performance of basic operations including string handling, hash tables, math generics, simple arithmetic, sorting, file scanning and (for C#) platform invoke of native code. These are the conclusions:

There is only a small performance penalty for C# on the desktop versus C++. Mono is generally slower than

Common sense on Windows 8, Silverlight and .NET

I am wary about writing another post on this subject in the absence of any further news, but since there is a lot of speculation out there I thought it would be worth making a few further observations.

Will Windows 8 support Silverlight and/or some other variety of .NET in its new touch-centric mode? I

Full circle at Microsoft: from the early days of .NET to the new Chakra JavaScript engine

A discussion with a friend about the origins of Microsoft’s .NET runtime prompted a little research. How did it come about?

A quick search does not throw up any detailed accounts. Part of the problem is that much of it is internal Microsoft history, confidential at the time.

One strand, mentioned here, is Colusa’s OmniVM:

Considering Windows 8 as an HTML platform

Amongst all the fuss about whether Microsoft is deprecating Silverlight or even client-side .NET, it is easy to lose sight of the other angle on this. What are the implications of Microsoft embracing HTML and JavaScript as a new first-class Windows development platform? Here’s the quote again:

Today, we also talked a bit about how
