Anysphere Dev Container extension keeps begging to be installed

Describe the Bug

Every time I reload my window, Cursor pops up a notification to suggest installing the Anysphere Dev Containers extension. But it is already installed.

I suspect it is because my extensions.json ALSO lists the MS version ms-vscode-remote.remote-containers, which is obviously NOT installed because it is NOT available in the Cursor extension marketplace.

I guess you guys did some magic to make your version of this extension appear as recommended when theirs is listed. But you forgot to skip when yours is already installed.

I list both in extensions.json because other devs may prefer to use VS Code. As far as I understand it should be one or the other. Theirs won’t appear in your marketplace, and yours won’t appear in their marketplace.

Steps to Reproduce

  • Add anysphere.remote-containers AND ms-vscode-remote.remote-containers to extensions.json
  • Install the Anysphere Dev Containers Extension
  • Reload Cursor
  • Observe the notification suggesting to install Anysphere Dev Containers extension (already installed)

Expected Behavior

Do not bug me to install extensions that are already installed.

Does this stop you from using Cursor

No - Cursor works, but with this issue
