How To Check .Net Version: A Simple Guide

Determining the version of Microsoft .NET installed on a system, whether Windows or otherwise, can be useful for developers, system administrators, and users alike. .NET is a free and open-source software framework developed by Microsoft that runs primarily on Microsoft Windows. It is used to develop a wide range of applications, from simple command-line tools to complex enterprise applications. Knowing the version of .NET installed can be important for ensuring compatibility with specific applications or libraries, troubleshooting issues, or simply staying up-to-date with the latest features and security patches. There are several methods to check the version of .NET installed on a system.

One of the simplest methods to check the version of .NET installed on a Windows system is to use the command prompt. Open the command prompt by typing “cmd” into the search bar and selecting the Command Prompt application. Once the command prompt is open, type the following command:

dotnet –version

This command will display the version of .NET installed on the system. If .NET is not installed, the command prompt will display an error message.

Another method to check the version of .NET installed on a Windows system is to use the registry. The registry is a database that stores configuration settings for the operating system and installed applications. To access the registry, open the Registry Editor by typing “regedit” into the search bar and selecting the Registry Editor application. Once the Registry Editor is open, navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\

The value of the “Version” key in this registry key will be the version of .NET installed on the system. If .NET is not installed, this key will not exist.

There are also several methods to check the version of .NET installed on a non-Windows system. One method is to use the .NET Core CLI, which is a cross-platform command-line tool for managing .NET Core applications. To use the .NET Core CLI, open a terminal window and type the following command:

dotnet –version

This command will display the version of .NET Core installed on the system. If .NET Core is not installed, the terminal window will display an error message.

Another method to check the version of .NET installed on a non-Windows system is to use the .NET Framework SDK, which is a set of tools for developing and deploying .NET applications. To use the .NET Framework SDK, open a terminal window and type the following command:

reg query “HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP” /s

This command will display a list of all installed versions of the .NET Framework SDK. If the .NET Framework SDK is not installed, the terminal window will display an error message.

Knowing how to check the version of .NET installed on a system is a useful skill for developers, system administrators, and users alike. By following the steps outlined in this article, you can easily determine the version of .NET installed on your system and ensure that you have the latest version installed.

1. Command Prompt
