new features 4.5 Added in 4.5: Ability to reduce system restarts by detecting and closing .NET Framework 4 applications during deployment. See Reducing System Restarts During .NET Framework 4.5 Installations. Support for arrays that are larger than 2 gigabytes (GB) on 64-bit platforms. This feature can be enabled in the application configuration file. See the element, which also lists other restrictions on object size and array size. Better performance through background garbage collection for servers. When you use server garbage collection in the .NET Framework 4.5, background garbage collection is automatically enabled. See the Background Server Garbage Collection section of the Fundamentals of Garbage Collection topic. Background just-in-time (JIT) compilation, which is optionally available on multi-core processors to improve application performance. See ProfileOptimization. Ability to limit how long the regular expression engine will attempt to resolve a regular expression before it times out. See the Regex.MatchTimeout property. Ability to define the default culture for an application domain. See the CultureInfo class. Console support for Unicode (UTF-16) encoding. See the Console class. Support for versioning of cultural string ordering and comparison data. See the SortVersion class. Better performance when retrieving resources. See Packaging and Deploying Resources in Desktop Apps. Zip compression improvements to reduce the size of a compressed file. See the System.IO.Compression namespace. Ability to customize a reflection context to override default reflection behavior through the CustomReflectionContext class. Support for the 2008 version of the Internationalized Domain Names in Applications (IDNA) standard when the System.Globalization.IdnMapping class is used on Windows 8. Delegation of string comparison to the operating system, which implements Unicode 6.0, when the .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.x. 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. See Element. Type reflection support split between Type and TypeInfo classes. See Reflection in the .NET Framework for Windows Store Apps.
