How .NET 4 versions helps to prepare for the latest apps and services for the upcoming .NET vNext

.NET is a programming framework that was created by Microsoft that  developers could use to easily build applications. In addition, it provides apps in an orderly fashion to access web services, databases and other communication tool. Through the years there has been many updates and new versions of the framework that was created.

N 2At present, NET vNext is not here yet as it is still being developed and polished, but Microsoft wants programmers and developers to move on to the version 4.5.2 as soon as  possible, with the reinforcement for versions 4 up to 4.5.1 ending in the middle of January 2016. While vNext is getting polished for availability sometime next year, there is still the business of making certain the services and apps continue to move along and adopt the greatest and the latest, which means relegating legacy applications to the past. The framework Fundamentals Team provides fair warning over a year in advance of ending support for version 4.5.1 and outdated. Microsoft has announced to change its product lifecycle support policy, but only for the older versions.

Early in May of this year, the most recent version is 4.5.2 which mostly came with several new features. These include new and enhanced APIs, enhancements in building Windows forms, improved shared hosting and enhanced Async. It was released as an in-place update rapidly after 4.5.1. Changes to the framework are being made much faster, and the regularity of updates could often mean that the latest features, fixes and innovations are available in the current version and not in the legacy variants.

Microsoft would be minimizing the product lifecycles of the older models and imposing a Jan. 12, 2016 end-of-extended sustennance date on them. The older versions would have the same extended support lifecycles as the server products which run on them. However, Microsoft would impose what would amount to be an earlier end-of-support date in those instances. .NET 4.5.2 is considered as an ‘in-place update’ to the system family, without having to recompile applications.

The transition to newer editions will not be entirely smooth and there are some changes included in new releases that could be deemed as breaking changes because of incompatibility with senior ones. These are only included in the interests of security, to comply with industry-wide standards and to correct a previous incompatibility within the program. Versions of Windows Server 2008 and SQL Server 2008 still rely on the 3.5 framework of Server 2008 and has extended support until the year 2020. Thus, in a specific twist, servers that run the older 3.5 could have a longer product lifecycle compared to those running the older 4 and 4.5 variants.

All of the work is aimed to get programmers and developers up ahead on  vNext. This highlights .NET to a mobile-first, cloud-first platform. It is a slimmed-down update which runs libraries based on user environment and deploys infrastructure and runtime libraries as applications require them. A cloud-optimized mode does not include WPF or Windows Presentation Foundation and Windows Forms libraries, for instance.
