Live Share now included in Visual Studio 2019, available for VS Code
Along with this release, we’re excited to have partnered with a few 3rd party extensions to enhance the Live Share experience in Visual Studio. One of the biggest feature requests we’ve received has been to include integrated chat, and with CodeStream, you get a companion chat experience within a Live Share session. With Live Share installed by default in Visual Studio 2019, it’s easy to get started collaborating with your team.
