How to understand the functional features of NET Framework 4.0. in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.
Developers living in this era are happy and busy. Because they will get a good programming environment for the release of a new tool and need to invest a lot of time and energy to learn the tool. Microsoft has released Beta 2 beta versions of Visual Studio 2010 and .NET Framework 4.0. Microsoft has stuffed a lot of new things into. NET Framework 4.0. some of them are really good, but some still feel a little rough, still in the experimental stage, and are not very practical.
A brief review of history,. Net Framework 1.1 is actually an experiment,. Net Framework really matured from 2.0, and then the Framework 3 Framework Framework 3.5 is actually based on the extension of Framework 2. Framework 3 + Framework 3 SP1 in addition to correcting some Framework 2 bug, the main extension is the addition of 3W framework, which is WPF,WCF,WWF. F3.5 is similar to F3, except for the previous Bug, the main extension is: LINQ,WF,WCF,Add-in (which will be replaced by MEF in the future). Framework 3.5 SP1, a few new things have been added: MVC,Dynamic Data,Entity Framework,Data Services and so on.
Of course, we can't ignore the language improvements made by Framework 3, such as Linq,Lambda, extension functions, the use of var types, and so on.
So let's take a look at what the .NET Framework 4.0 feature has brought us.
.net Framework 4 works in parallel with Framework 3.5 SP1. Applications that can be run in older versions of Framework will continue to be able to run on .NET Framework 4.
There are innovations in Visual Basic and C # languages, such as declaring lambdas, hidden line continuations, dynamic scheduling, and naming / optional parameters, etc.
Many new functions have been added to the ADO.NET entity framework to simplify the developer's relational database program by improving the level of abstraction. These new features include persistent neglect, POCO support, delayed loading, support for test-driven development, functional models, and new LINQ operators.
Net Framework 4.0Function 1. The following are improvements in ASP.NET:
Improved JavaScript user interface templates and data binding in AJAX
Improve the chart control of ASP.NET
.net Framework 4.0Function 2. The following are improvements in WPF:
Add support for Windows 7 multi-touch, ribbon control and taskbar extension in WPF
Add Surface 2.0 SDK support to WPF
New line of business controls, including chart controls, intelligent editing, data grids, and other controls that can improve the experience of developers who "build applications for data centers".
Improve performance and scalability
Add visualization improvements to text, pixel layout, localization, and interoperability
Third, the improvements in Windows Workflow (WF) give developers more control over their workflow, including the following:
Improve the activity planning model
Improve the design experience
A new way of process modeling
Expand the range of activities of the palette
Integration of workflow rules
New mail-related features.
.net Framework 4.0..NET Framework also provides significant performance improvements for WF-based workflows:
Improve the Windows communication infrastructure (WCF) architecture, such as streaming service related support, persistence of two-way communication, etc.
The .NET Framework 4 also provides new WCF features, such as service discovery, router services, simplified configuration, REST support, diagnostics, and performance improvements.
This is the answer to the question about how to understand the functional features of NET Framework 4.0.I hope the above content can help you to a certain extent, if you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
