Hi @Antonio, David Albert,
Welcome to Microsoft Q&A!
For Visual Studio Code Dev Containers, you can check its license. It is installed in Visual Studio Code instead of Visual Studio. If you have a license for Visual Studio Code, you can use the extension.
If you have more questions, please post it to the Stack Overview tagged visual-studio-code forum or GitHub repository where you would get professional support for this product.
Thanks for your understanding.
Sincerely,
Anna
