• If this PR is a new feature, please provide at least one example link
• Make sure all of the significant new logic is covered by tests

This builds on #785 so the Sdk attribute is also handled now.

CI stucks , most likely caused by the force push. Maybe best to recreate the commit from scratch

[xt0rted]

It wasn't running before the force push. The workflow might need to be adjusted to something like this:

on:
  push:
    branches:
      - master
  pull_request:

That's how I set it up for GitHub Dark so it'd handle pushes to master, PRs from local branches, and PRs from forks.

Running on [push, pull_request] was causing extra runs when I'd create PRs so the branch filter was added to fix that.

A few minutes ago I remove the pull_request flag 8feff6f since I was annoyed by the extra run 😆 Thanks for sharing this template. Will update the workflow straight away

@stefanbuck I forgot the sdk value could contain multiple values like this Sdk="Microsoft.NET.Sdk;Microsoft.NET.Sdk.Publish". Is it possible to split these and create a link for each one?

[stefanbuck]

That might be tricky. I need to look into this myself before I can say anything useful 😉

[stefanbuck]

I looked into it and it's rather complicated to make this work. The current OctoLinker architecture is based on the assumption that each RegExp returns just one result. Changing this requires some larger rewrites down the line. Most likely not worth the effort.

From what I know having multiple values for this isn't common. I've never seen it done in a project outside of my own so I doubt many people would hit this.
