How to get intellisense in Visual Studio Code for Unity functions names?

To enable IntelliSense for Unity function names in Visual Studio Code, follow these steps:

1. Install .NET SDK and .NET Framework.
   • Make sure you have the .NET SDK and .NET Framework installed on your system. You can download them from the Microsoft website. You can check if you have the necessary components installed by typing dotnet in VSCode’s terminal.
   • Ensure you have the .NET Framework Developer Pack installed. This is needed to resolve the error:

   The reference assemblies for .NETFramework,Version=v4.7.1 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application.

2. Update VSCode.
   • Update Visual Studio Code to the latest version.
3. Install the C# for Visual Studio Code extension.
   • Open Visual Studio Code and go to the Extensions tab.
   • Search for the "C# for Visual Studio Code" extension and install it.
4. Install the Visual Studio Code Editor package in Unity.
   • Open Unity and go to Package Manager > All.
   • Search for the "Visual Studio Code Editor" package and install it.
5. Configure Unity to use Visual Studio Code as the external script editor.
   • Go to Edit > Preferences > External Tools in Unity.
   • Select Visual Studio Code as the External Script Editor.
   • Ensure the "Regenerate project files" checkbox is ticked.
6. Restart Visual Studio Code.
   • Close and then reopen Visual Studio Code.
7. Open a C# script in Visual Studio Code.
   • In Unity, double-click on a C# script to open it in Visual Studio Code.

IntelliSense should now be enabled for Unity function names in Visual Studio Code.

Additional tips:

• Make sure that the solution file (.sln) is located in the same directory as the project folder.
• If you are still having problems, try disabling and then re-enabling the C# extension in Visual Studio Code.
• You may need to install additional extensions, such as Unity Snippets or Unity Tools, to get the full IntelliSense experience.

Note: If you are using macOS, you may need to set the omnisharp.useGlobalMono setting to always in your Visual Studio Code settings.
