Explore new ASP. NET technologies for more convenient Web development

ASP. net ajax, added new controls, new data capabilities of LINQ, and enhanced support for CSS, JavaScript, and other content. Web developers have taken a more important step.

New ASP. NET Technology 1. Use AJAX

Developers can quickly create flexible and responsive user interfaces. To implement these functions, you only need to add several server controls to the page. In the past, AJAX was just ASP. NET runtime extension, which is now integrated in. and can complete more cross-platform tasks, making it easier to create standard AJAX applications.

ASP. NET New Technology 2,LINQ solves the problem of the correspondence between objects and data.

. NET Framework 3.5 has added the LINQ query language. In the past, when we used SQL to query strings, it was always prone to errors. Now, LINQ provides a safer architecture for C # and VB, and provide more intelligent support. For Web applications, the LinqDataSource control in ASP. NET allows us to easily query, filter, and perform other data operations .. NET Framework 3.5 Other features include: HashSet set, DateTime offset support, diagnostics exception diagnosis) processing, garbage collection) set, better thread lock support, and so on.

Object-oriented is the mainstream technology in program development. When a relational database corresponds to an object-oriented development method, it needs to access the relational database in an object-oriented display mode. without assistance from tools, A considerable cost is required. It is common for general database applications to combine or reference multiple data tables. However, it is still very labor-consuming to use data in real time and flexibly using object-oriented technology. To solve this problem, there are currently two solutions: Architecture (Framework) level and program language level.

Currently, Hibernate, Borland ECO (Enterprise Core Objects), and Microsoft will launch ADO in the future. NET vNEXT, which is an architecture-level O/R Mapping (corresponding to an object and a relational database) solution. Architecture-level O/R Mapping has the disadvantages of difficult debugging, data correspondence, attribute Setting errors, and Object Query Language errors, problems are discovered during the execution phase.

ASP. NET Technology 3. in NET Framework 3.5, WCF supports creating Web services supported by most network standard protocols, such as SOAP, RSS, JSON, and pox.) whether you are using JSON to develop AJAX programs or RSS, or a standard SOAP Web service. WCF allows you to easily create terminal programs. Currently,. NET Framew ork 3.5 also supports creating Web services in the local information field similar to a typical host sharing environment.

ASP. NET New Technology 4. Visual Studio 2008 provides a new interface, which is consistent with VS's practice. The interface style changes every time ). VS2008 removes the designer and source code view, which makes opening the VS2008 interface faster than before. The new split view allows you to edit the HTML source code and view the page effect. The ability to support Cascading Style Sheets is greatly enhanced. Controls can be immediately displayed, which is also what WYSIWYG sees), and VS2008 supports nested master page development. In VS2008, the client no longer only supports standard JavaScript objects, but also automatically displays custom variables and methods and provides stronger script debugging functions.

ASP. NET New Technology 5. In previous VS versions, you can only create projects under one version. For example, you can only create projects of Version 2.0 or version 1.1.) In VS2008, we can include multiple versions, with a simple pull-down operation, you can decide which version of the project to create includes 2.0, 3.0, 3.5 ). No matter which version you use, you can use the new functions provided by VS2008. For example, in Web development, you can use JavaScript support provided by VS2008 in the old project.
