The .NET Framework 4 Client Profile includes the following new features and improvements:
- Improvements in CLR and BCL
Performance improvement including better multicore support, background garbage collection, and profiler attach on server.
New memory mapped file and numeric types
Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.
- Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
- Improvements in ADO.NET
Entity Framework, which simplifies how developers program against relational databases by raising the level of abstraction. The Entity Framework has many new features in the .NET 4 Framework. These features include persistence ignorance and POCO support, Foreign Key Associations, lazy loading, test-driven development support, functions in model, and new LINQ operators.
Data Services framework consists of a combination of patterns and libraries that enable the consumption of REST-based data services for the web. ADO.NET Data Services has many new features in the .NET 4 Framework. These features include: enhanced BLOB support, Data Binding, Row Count, Feed Customization, Projections, and Request Pipeline improvements. Built-in integration in Microsoft Office 2010 now makes it possible to expose Microsoft Office SharePoint Server data as a data service and access that data using the ADO.NET Data Services client library.
- Improvements in WPF
Added support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
Added support for Surface 2.0 SDK.
New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.
Improvements in performance and scalability.
Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.
- New Windows Workflow (WF) that includes an improved activity programming model, an improved designer experience, a new flowchart modeling style, an expanded activity palette, and new message correlation features. The .NET Framework 4 also offers significant performance gains for WF-based workflows.
- Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support. Additionally, .NET Framework 4 provides new WCF features such as service discovery, routing service, REST support, diagnostics, and performance.
- Innovative new parallel-programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors.
