How do I open multiple projects/folders in a single Visual Studio Code instance, and open multiple files in single view? Does it has any option for future change request?
You can use this extension known as Project Manager
In this the projects are saved in a file projects.json, just save the project and by pressing Shift + Alt + P
you can see the list of all your saved projects, from there you can easily switch your projects.
Not sure why the simplest solution is not mentioned. You can simply do File>New Window
and open the other project in the new window.
Or you can just select multiple folders and then click open.
Go to File> Open Folder, then select multiple folders you want to open and click Select Folder
you can create a workspace and put folders in that : File > save workspace as and drag and drop your folders in saved workspace
Multiple Folders in VS
Click ->File ->Add Folder to Workplace.
Step 1.
Choose which project to work ->Add(press)
Step 2.
What I suggest for now is to create symlinks in a folder, since VSCode isn't supporting that feature.
First, make a folder called whatever you'd like it to be.
$ mkdir random_project_folder
$ cd random_project_folder
$ ln -s /path/to/folder1/you/want/to/open folder1
$ ln -s /path/to/folder2/you/want/to/open folder2
$ ln -s /path/to/folder3/you/want/to/open folder3
$ code .
And you'll see your folders in the same VSCode window.
