For more information, see Dynamic Language Runtime Overview. Several generic interfaces and delegates now support covariance and contravariance. For more information, see Covariance and Contravariance in Generics. BigInteger structure is an arbitrary-precision integer data type that supports all the standard integer operations, including bit manipulation.
It can be used from any. NET Framework language. In addition, some of the new. Complex structure represents a complex number that supports arithmetic and trigonometric operations with complex numbers. NET Framework 4 provides the System. Tuple class for creating tuple objects that contain structured data.
It also provides generic tuple classes to support tuples that have from one to eight components that is, singletons through octuples. To support tuple objects that have nine or more components, there is a generic tuple class with seven type parameters and an eighth parameter of any tuple type. New file enumeration methods improve the performance of applications that access large file directories or that iterate through the lines in large files.
For more information, see How to: Enumerate Directories and Files. NET Framework now supports memory-mapped files. You can use memory-mapped files to edit very large files and to create shared memory for interprocess communication. You can identify bit operating systems and processes with the Environment.
Is64BitOperatingSystem and Environment. Is64BitProcess properties. You can specify a bit or bit view of the registry with the Microsoft. RegistryView enumeration when you open base keys. The following list describes additional new capabilities, improvements, and conveniences. Several of these are based on customer suggestions. NET Framework 4 that helps you build extensible and composable applications. MEF enables you to specify points where an application can be extended, to expose services to offer to other extensible applications and to create parts for consumption by extensible applications.
It also enables easy discoverability of available parts based on metadata, without the need to load the assemblies for the parts. For more information, see Managed Extensibility Framework. For a list of the MEF types, see the System.
Composition namespace. Back to top. NET Framework 4 introduces a new programming model for writing multithreaded and asynchronous code that greatly simplifies the work of application and library developers. The new model enables developers to write efficient, fine-grained, and scalable parallel code in a natural idiom without having to work directly with threads or the thread pool.
Tasks namespace and other related types support this new model. For more information, see Parallel Programming in the. NET provides new features for the Entity Framework, including persistence-ignorant objects, functions in LINQ queries, and customized object layer code generation.
For ASP. NET 4, Dynamic Data has been enhanced to give you even more power for quickly building data-driven Web sites. This includes the following:. So why not downgrade to the version you love? When you upload software to oldversion. For every field that is filled out correctly, points will be rewarded, some fields are optional but the more you provide the more you will get rewarded!
So why not upload a peice software today, share with others and get rewarded! Welcome Guest, Login Register. Get Updates on. Net Framework Tweet. File Size: Application Compatibility and Deployment The. Client Profile The. In-Process Side-by-Side Execution This feature enables an application to load and start multiple versions of the.

Code Contracts Code contracts let you specify contractual information that is not represented by a method's or type's signature alone. Covariance and Contravariance Several generic interfaces and delegates now support covariance and contravariance. Tuples The. File System Enumeration Improvements New file enumeration methods improve the performance of applications that access large file directories or that iterate through the lines in large files.
Memory-Mapped Files The. Other New Features The following list describes additional new capabilities, improvements, and conveniences. To support culture-sensitive formatting, the System. The new String. IsNullOrWhiteSpace method indicates whether a string is null, empty, or consists only of white-space characters. New overloads have been added to the String. Concat and String.
Join methods that concatenate members of System. IEnumerable Of T collections. The String. Concat method lets you concatenate each element in an enumerable collection without first converting the elements to strings. Two new convenience methods are available: StringBuilder. Clear and Stopwatch. The new Enum. HasFlag method determines whether one or more bit fields or flags are set in an enumeration value. The Enum. Core New Features and Improvements The following features and improvements were added to the common language runtime and to.
NET Framework classes: Ability to reduce system restarts by detecting and closing. NET Framework 4 applications during deployment. See Reducing System Restarts During. Support for arrays that are larger than 2 gigabytes GB on bit platforms. This feature can be enabled in the application configuration file. Better performance through background garbage collection for servers. When you use server garbage collection in the. Background just-in-time JIT compilation, which is optionally available on multi-core processors to improve application performance.
Ability to limit how long the regular expression engine will attempt to resolve a regular expression before it times out. See the RegexMatchTimeoutproperty. Ability to define the default culture for an application domain. See the CultureInfo class.
Console support for Unicode UTF encoding. See the Console class. Support for versioning of cultural string ordering and comparison data. See the SortVersion class. Better performance when retrieving resources. Zip compression improvements to reduce the size of a compressed file. See the System. Compression namespace. Ability to customize a reflection context to override default reflection behavior through the CustomReflectionContext class.
Delegation of string comparison to the operating system, which implements Unicode 6. NET Framework is used on Windows 8. When running on other platforms, the. NET Framework includes its own string comparison data, which implements Unicode 5. See the String class and the Remarks section of the SortVersion class. Ability to compute the hash codes for strings on a per application domain basis.
Convention-based programming model that enables you to create parts based on naming conventions rather than attributes.
Multiple scopes. A subset of MEF that you can use when you create Metro style apps. This subset is available as a downloadable package from the NuGet Gallery. To install the package, open your project in Visual Studio , choose Manage NuGet Packages from the Project menu, and search online for the Microsoft. Composition package.

Tools Resource File Generator Resgen. Parallel Computing The. Web ASP. Support for model binders in Web Forms. These let you bind data controls directly to messaging. A client sends a message to a service and expects no response from the service. These new features include: State machine workflows, which were first introduced as part of the. This update included several new classes and activities that enabled developers to create state machine workflows.
These classes and activities were updated for the. The ability to copy and paste transitions in the workflow designer. Designer support for shared trigger transition creation. Activities for creating state machine workflows, including: StateMachine, State, and Transition. Ability to automatically create a Sequence activity when a second child activity is added to a container activity, and to include both activities in the Sequence activity.
