Extensions in Vscode are failing to function properly when multiple instances are open

I have been experimenting with creating a VsCode Extension using typescript and I encountered an issue while trying to track all the activities using events. Specifically, I set up listeners for when a file is opened so that an event is triggered and the file name is written to the console. However, this setup does not work when I open another instance of vscode using the File->New Window option. Could someone please explain why this behavior is occurring?

Answer №1

When launching a new window from the Extension Development Host instance, it behaves just like opening a window from a regular instance. The difference is that the new window does not display the tag [Extension Development Host]. This is because the new window has no knowledge of your extension as it is not officially installed.

The only workaround is to manually copy your extension into the extensions folder and test it out by "temporarily installing" it in the development host.
