Microsoft.NET Framework (.NET Programming Framework) v4.0 Simplified Chinese Version (32+64)

The.NET Framework is a comprehensive and consistent programming model developed by Microsoft for generating applications with visually stunning user experiences, seamless secure communication, and the ability to model a range of business processes. .NET Framework 4 will work in parallel with older Framework versions. By default, applications based on earlier versions of the Framework will continue to run on the target version. Microsoft.NET Framework 4 provides the following new features and improvements: Improved Common Language Runtime (CLR) and Base Class Library (BCL) Performance improvements, including better multi-core support, background garbage collection, and profiler attachment on the server. New memory mapped file and number types. Easier debugging, including dump debugging, Watson mini-dump, 64-bit mixed-mode debugging, and code protocols. Innovations in Visual Basic and C# languages such as lambda statements, implicit line continuation, dynamic scheduling, and named/optional parameters. Data Access and Modeling Improvements With the Entity Framework, developers can program relational databases using.NET Object and Language Integrated Query (LINQ). It has several new features, including persistence ignore and POCO support, foreign key association, lazy loading, test-driven development support, functions in models, and new LINQ operators. Other features include: better N-layer support with self-tracking entities, customizable code generation using the T4 template, model first development, improved designer experience, better performance, and complex form of entity sets. The WCF data service is a component of the.NET Framework that allows you to create REST-based services and applications to expose and consume data on the Web using the Open Data Protocol (OData). The WCF data service has several new features, including enhanced BLOB support, data binding, row counting, source definition, projection, and request pipeline improvements. The current built-in integration with Microsoft Office 2010 exposes Microsoft Office SharePoint Server data as an OData source and accesses that data source using the WCF Data Services client library. ASP.NET enhancements have more control over HTML, element ids, and custom CSS to make it easier to create standards-compliant, SEO-friendly Web forms. New dynamic data capabilities, including new query filters, Entity templates, richer support for Entity Framework 4, and validation and templating capabilities that can be easily applied to existing Web forms. Improved Web forms support for the new AJAX library, including built-in support for content delivery networks (CDN). Improvements to Windows Presentation Foundation (WPF) add support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility. Added support for Surface 2.0 SDK. New line-of-business controls, including chart controls, smart editing, data grids, and others to improve the developer experience for building data-centric applications. Performance and scalability improvements. Visual improvements in text clarity, layout pixel alignment, localization, and interoperability. Windows Workflow (WF) improvements that enable developers to better host and interact with workflows. These improvements include: an improved activity programming model, an improved designer experience, new flowchart modeling styles, expanded activity panels, workflow rule integration, and new message-related capabilities. The.NET Framework 4 also significantly improves the performance of WF-based workflows. Windows Communication Foundation (WCF) improvements, such as support for WCF workflow services (enabling workflow programs with messaging activities) and related support. In addition,.NET Framework 4 provides new WCF capabilities such as service discovery, routing services, REST support, diagnostics, and performance. About innovative new parallel programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordinated data structures that allow developers to take advantage of multi-core processors. This is Microsoft's official Microsoft.NET Framework 4 (standalone installer)
