3.1.400 [/usr/local/share/dotnet/sdk]
5.0.100 [/usr/local/share/dotnet/sdk]
6.0.302 [/usr/local/share/dotnet/sdk]

This indicates that you have .NET SDK versions 3.1.400, 5.0.100, and 6.0.302 installed. Knowing the installation paths can be useful if you need to manually manage or configure these SDKs. Furthermore, this command allows you to quickly identify any outdated or unnecessary SDKs that may be taking up valuable disk space. By regularly reviewing the output of dotnet --list-sdks, you can maintain a clean and organized development environment, ensuring that you're only using the SDKs that are necessary for your projects. This practice not only improves the efficiency of your development workflow but also reduces the risk of conflicts between different SDK versions. Additionally, understanding the output of this command can help you troubleshoot issues related to SDK configurations, such as incorrect environment variables or missing dependencies. Therefore, make it a habit to use dotnet --list-sdks to stay informed about the SDKs installed on your system and ensure that they are properly managed. By doing so, you'll be able to maintain a stable and efficient development environment, allowing you to focus on building great .NET applications.

Method 3: Checking the .csproj File

If you're working on a specific .NET project, you can also check the .csproj file to determine the target framework. This method is useful when you want to know the .NET version that a particular project is using.

1. Locate the .csproj File: Find the .csproj file in your project directory. This file contains information about your project, including the target framework.
