Do i still Need Microsoft Silverlight? > 자유게시판

Looking the World Vast Net has modified too much because the early nineties. Back then, most Net pages consisted of static textual content, a couple of pictures and the occasional looping (and often irritating) MIDI sound file. But the online has grown more complicated over time. Right now, you'll be able to go to Web pages that incorporate video, animation, sound and interactive features. With probably the most superior Web pages, Memory Wave it's virtually like getting pulled right into a movie. However in order to build, view and interact with these new options, programmers have had to create new applications. One of those applications is Microsoft's program Silverlight. Silverlight defies easy rationalization. In many ways, it's just like Adobe Flash. Silverlight requires developers and users to obtain a shopper -- Net browsers can't course of Silverlight content with out this download. It gives Web developers the ability to include streaming video, audio and animation into Web pages. Programmers can create advanced, consumer-interactive Internet purposes utilizing Silverlight know-how. On the World Vast Net, these applications have a special title: Wealthy Internet Applications (RIAs).

Internet browsers may eventually evolve into fully-fledged Net-based operating techniques as we use the Web to supply our data processing and storage wants. Leveraging the Web in this manner known as cloud computing -- applications and data dwell within the "cloud" of the Internet as a substitute of on a person user's machine. Silverlight is just one in all dozens of instruments designed to assist programmers create better RIAs. Microsoft engineers constructed Silverlight as an extension of different Microsoft initiatives, but the appliance itself stands by itself. Microsoft promotes Silverlight as a cross-platform, cross-browser expertise. That means Silverlight applications ought to work on either PCs or Mac computers and inside browsers like Web Explorer, Firefox or Safari. Silverlight should quickly work with Linux computer systems as nicely -- an open-source undertaking referred to as Mono is spearheading the hassle to create a Linux model. Although Silverlight is a young technology, it's no stranger to hassle or controversy.

Some developers and users aren't eager on yet one more Web expertise that requires a downloadable plug-in to work. And a partnership with NBC in the course of the 2008 Beijing Olympics won't have generated as a lot buzz as Microsoft hoped. But before we leap into all of that, let's first take a closer look beneath Silverlight's hood. Silverlight 1 helps functions written in the JavaScript programming language. Visual Basic. Both versions of Silverlight work throughout the .Net framework. So what's .Web? It's another product from Microsoft. The .Web framework is a programming model. Programmers can build functions inside this model -- particularly Web functions that rely on eXtensible Markup Language (XML).Web Framework's two major components are a standard language runtime and a category library. The widespread language runtime acts like an administrator -- it screens applications and allocates the resources those purposes want (like Memory Wave Routine or processing energy) to run properly. The category library contains a number of reusable software objects programmers can depend on while creating applications.

A software program object has two characteristics: state and Memory Wave behavior. An object's state refers back to the totally different conditions the object can have. For example, Memory Wave Routine a program may have the states of "working," "paused" and "stopped" (though not all at the same time). Behaviors confer with what an object can do. And that is just the framework that surrounds Silverlight! Within Silverlight, Microsoft contains Home windows Presentation Foundation (WPF) expertise and help for eXtensible Application Markup Language (XAML). Application developers can use each WPF and XAML to create Web purposes. Both WPF and XAML work seamlessly within the .Internet framework. Microsoft developed WPF because Hypertext Markup Language (HTML) has limitations -- Net browsers are capable of executing capabilities which might be too complex for HTML to help. WPF uses a vector-primarily based rendering engine to generate graphics for functions. The primary function of XAML is to offer builders the means to tweak the appearance of their applications. Collectively, WPF and XAML outline the look and behavior of a Silverlight application.
