The .NET Framework is a software development platform developed by Microsoft. It is made up of programming languages, libraries and tools for developers to build Windows applications such as games, web apps, etc. .NET Framework is also required to be installed in Windows in order to run an application built with .NET Framework.A software built with a specific version of .NET Framework will require exactly the same version of .NET Framework to be installed on the Windows in order for it to run successfully. For example, if a game or app is built with .NET Framework version 4.8, you will need to install .NET Framework Runtime 4.8 in order to run the software.Besides, .NET Framework is backward compatible. It means that the latest version of .NET Framework will includes all previous versions. For instance, if you install .NET Framework 4.8, you should also be able to run apps that requires older versions of .NET Framework such as 4.7, 4.6, 4.5, etc.However, there are some exceptions where software may require explicitly a specific .NET Framework version in order to run. You will need to install the required version of .NET Framework in order to run the software successfully.If you are not sure what version of .NET Framework is installed on your Windows, this guide will show you 3 methods on how to check .NET Framework version in Windows 11.Method 1: Check .NET Framework version using PowerShell commandDotNetVersionListerCheck .NET version using Get-ChildItem commandMethod 2: Check .NET version via Command PromptMethod 3: Check .NET version through File ExplorerMethod 1: Check .NET Framework version using PowerShell commandIn Windows 11, you can execute a few lines of PowerShell commands to quickly check all the versions (including older versions) of .NET Framework ever installed on your PC. There is a Windows built-in command and also a community command-line tool you can use to check the .NET Framework version in Windows.We recommend to try using the community tool called DotNetVersionLister first. If it doesn’t work, use the built-in command. You can execute these PowerShell commands in either Windows PowerShell or Windows Terminal (Windows 11) with administrative privileges.DotNetVersionListerThe
