• GitHub Extension for Visual Studio version: 2.3.4.54
• Visual Studio version: 15.4.2

Repro:

1. Open solution that is in a git repo from our GitHub Enterprise.
2. Open any code (.cs) file (or .config, for instance).
3. Right-click on any line to view the context menu.

Expected: See a GitHub -> menu that has an Open/Link to GitHub link that will take me to the corresponding line in the repo/branch that I'm on at the time.

Actual: No GitHub menu.

Notes: I reported this to Phil Haack and he looped in Andreia Gaita on Twitter. She suggested I report this here.

Will email logs.
