How do I use it?
After installing, VS Code will have a Sonatype Scan Results pane which will show the current scan results. Clicking on entries will pull up more details about the selected version. It will run scans against OSS Index by default, and you can use the Settings to point to Nexus IQ if you have one available.
I apologize for the redirect, but the community around the plugin is managing the feature requests in GitHub at Issues · sonatype-nexus-community/vscode-iq-plugin · GitHub. I suggest creating an issue there to represent your interest in .NET Core.
