IE9 is coming!

admin — Thu, 19 Nov 2009 09:07:45 +0000

Good news for all of us who havent upgraded to IE8 yet. Internet Explored 9 is on its way! The web browser would be coming with great performance upgrades.

Browser performance involves many different sub-systems within the browser. Different sites – and different activities within the same site – place different loads and demands on the browser.

Developers want more capabilities in the browser to build great apps and experiences; they want them to work in an interoperable way so they don’t have to re-write and re-test their sites again and again. The standards process offers a good means to that end.

As engineers, when we want to assess progress, we develop a test suite that exercises the breadth and depth of functionality. With IE8, we delivered a highly-interoperable implementation of CSS 2.1 and contributed over 7,200 tests to the W3C. Standards that do not include validation tests are much more difficult to implement consistently, and more difficult for site developers to rely on.

Some standards tests – like Acid3 – have become widely used as shorthand for standards compliance, even with some shortcomings. Acid3 tests about 100 aspects of different technologies (many still in the “working draft” stage of standardization), including many edge cases and error conditions.

.Net Framework 4.0 new features

admin — Mon, 26 Oct 2009 09:12:05 +0000

.Net Framework 4.0 adds also some new and cool features to file system objects. File class has now ReadLines() methods that returns IEnumerable. WriteAllLines() methods has two overload methods that accept IEnumerable instead of strings array that was also supported in previous versions of .Net Framework. This posting introduces ReadLines() and WriteAllLines() methods and gives you some ideas how to use these methods in your applications.

Also the new .Net Framework 4.0 Beta 2 has new IsNullOrWhiteSpace() method for strings generalizes IsNullOrEmpty() method to incluse also other white space besides empty string. In this posting I will show you simple example that illustrates how to use IsNullOrWhiteSpace() method.

.Net Framework 4.0 Beta 2 introduces new class in System.Numerics namespace: Complex. Complex represents complex numbers and enables different arithmetic operations with complex numbers. In this posting I will show you how to use complex numbers in .Net Framework 4.0 applications.

Complex class has two constructors – one of them has no arguments and the other takes real and complex parts of complex number. Complex numbers have also properties for phase and magnitude. Let’s see the following code.

Here is a more complete list:
* Complex Number
* Location
* IObservable
* Stream.CopyTo
* Guid.TryParse, Version.TryParse, and Enum.TryParse
* Enum.HasFlag
* String.Concat and String.Join overloads that take IEnumerable
* String.IsNullOrWhiteSpace
* Environment.SpecialFolder additions
* Environment.Is64BitProcess and Environment.Is64BitOperatingSystem
* Path.Combine params support
* TimeSpan Globalized Formatting and Parsing
* Stopwatch.Restart
* StringBuilder.Clear
* IntPtr and UIntPtr Addition and Subtraction operators
* ServiceProcessInstaller.DelayedAutoStart
* ObservableCollection moved to System.dll

admin — Wed, 21 Oct 2009 08:40:03 +0000

Today from Microsoft released the links to download the new Visual Studio 2010 Beta 2 and .NET Framework 4 Beta 2!

Here is the link.

VS 2010 Product Line SKU Simplifications

With VS 2010 we are simplifying the product lineup and pricing options of Visual Studio, as well as adding new benefits for MSDN subscribers. With VS 2010 we will now ship a simpler set of SKU options:

* Visual Studio Express: Free Express SKUs for Web, VB, C#, and C++

* Visual Studio 2010 Professional with MSDN: Professional development tools as you are used to today with the addition of source control integration, bug tracking, build automation, and more. It also includes 50 hours/month of Azure cloud computing.

* Visual Studio 2010 Premium with MSDN: Premium has everything in Professional plus advanced development tools (including richer profiling and debugging, code coverage, code analysis and testing prioritization), advanced database support, UI testing, and more. Rather than buying multiple “Team” SKUs like you would with VS 2008, you can now get this combination of features in one box with VS 2010. It also includes 100 hours/month of Azure cloud computing.

* Visual Studio 2010 Ultimate with MSDN: Ultimate has everything in Premium plus additional advanced features for developers, testers, and architects including features like Intellitrace (formerly Historical Debugging), the new architecture tools (UML, discovery), test lab management, etc. It also includes 250 hours/month of Azure cloud computing.

Side by Side Support with VS 2008

VS 2010 and .NET 4.0 can be installed side-by-side on the same machine as VS 2008 and .NET 3.5. You can install the Beta 2 version on a machine and it will not impact your existing VS 2008 / .NET 3.5 development.

Go-Live License Available

.NET 4 and VS 2010 Beta 2 include a “go-live” license which means you can start using the products for production projects.

URL Routing with Visual Studio 2010 and ASP.NET 4

admin — Tue, 13 Oct 2009 13:48:38 +0000

This can be achieved with the function MapPageRoute.

Introducing the Microsoft AJAX CDN

admin — Thu, 17 Sep 2009 07:48:43 +0000

Yesterday from Microsoft released the AJAX CDN. The Microsoft Ajax CDN enables you to significantly improve the performance of ASP.NET Web Forms and ASP.NET MVC applications that use ASP.NET AJAX or jQuery. The service is available for free, does not require any registration, and can be used for both commercial and non-commercial purposes.

ASP.NET 4.0 will make it especially easy for ASP.NET Web Forms developers to take advantage of the CDN. By setting one property of the ScriptManager control, you will be able to redirect all requests for the built-in ASP.NET JavaScript files to the CDN and improve the performance of your Web Forms applications.

You can get a full listing of the JavaScript libraries (and associated URLs) we already have loaded in our CDN cache here: www.asp.net/ajax/cdn

admin — Fri, 21 Aug 2009 07:27:47 +0000

I have found this post at somasegar’s blog writing about the new enhancements in VB and C# languages.

About VB.NET they include:
- removed the underscore (“_”) character when breaking a code statement across multiple lines
- simple way of declaring properties
- collection initializers and array literals are simpler as well
- better support for lambdas
- interoperating with dynamic language code such as Python and Ruby are simpler

Developer Evangelist Handbook

admin — Tue, 28 Jul 2009 21:14:04 +0000

Here is what I have found this late evening. The Developer Evangelist Handbook is something which is a good read from one side and serious role at every IT company.

This handbook will get you on the way to be a great developer evangelist for any product or company. Of course your approach needs tweaking for different markets and audiences - and in accordance with your own personality - but the main principles are the same for everybody and anywhere in the world.

Developer evangelism is a totally new field of work and the first hurdle you will encounter is people asking what a developer evangelist is and why any company would need a role like that.
