On older versions of Windows (think XP and Vista), you often had to uninstall and reinstall the various versions of. Since both required versions are included with Windows and installed as needed, app installations are pretty seamless. NET itself on modern versions of Windows. What Can I Do if I’m Having Problems with. You have options for adding version 3.5 and version 4.6 separately. You can actually add them to Windows yourself ahead of time if you want by accessing Windows’ optional features. They are installed on a first-time-needed basis, so the first time you install an app that needs one of those versions, Windows will add it automatically. Windows 8 and Windows 10 include versions 3.5 and 4 (the current version right now being 4.6.1). Windows pretty much handles it all for you. The good news is that you as a user don’t really have to worry about those installations anymore. Apps written to versions 3.5 and lower will require version 3.5 to be installed, and apps written to version 4 or higher will need version 4 installed. It’s designed so that it can be run alongside version 3.5 on the same PC. Version 4 (and up) does not feature backwards compatibility with older versions. When Windows 8 rolled around, a new, completely redesigned. RELATED: What Windows 10's "Optional Features" Do, and How to Turn Them On or Off Together, these two things meant that developers could now pretty much rely on users having the proper components already installed and no longer had to ask users to perform additional installations. Other developers can make sense of what a program is doing more easily and users of the applications can count on things like Open and Save As dialog boxes working the same in different applications. Using a framework of shared code like this also helps provide some standards between applications. Instead, they can focus on the code that’s unique to their applications and the user interface that ties it all together. This shared code makes the lives of developers much easier because they don’t have to reinvent the wheel every time their applications need to perform some common function. NET Framework contains tens of thousands of pieces of shared code. Instead of writing that code themselves, and then writing all the little bits and pieces that have to interpret what the ping results mean, they can use code from the library that performs that function.Īnd that’s just one tiny example. Say, for example, a developer needed their application to be able to ping another IP address on the network. The bits of code in the shared library can perform all kinds of different functions. NET Framework, that library of shared code is named the Framework Class Library (FCL). A framework (in programming terms) is really a collection of Application Programming Interfaces (APIs) and a shared library of code that developers can call when developing applications, so that they don’t have to write the code from scratch.

NET Framework 4.5 adds substantial improvements to other functional areas such as ASP.NET, Managed Extensibility Framework, Windows Communication Foundation, Windows Workflow Foundation, and Windows Identity Foundation. NET Framework 4.5 includes significant language and framework enhancements for C#, Visual Basic, and F# (so that you can more easily write asynchronous code), the blending of control flow in synchronous code, a responsive UI, and web app scalability. NET Framework 4.5 together with the C#, Visual Basic, or F# programming language, you can write Windows apps. NET Framework 4.5 is a highly compatible, in-place update to the. ![]()
