Notes

Occasionally users have been unable to install and/or uninstall the GitHub for Visual Studio extension. We've suspected the issue has something to do with some kind of incompatibility when the same version is on the Marketplace and VS Installer. There also appears to be an issue installing when the Marketplace version is earlier than the VS Installer version.

Unfortunately I don't currently have an exact repro. 😕

I noticed the following when attempting to uninstall the VS Installer version.

Here is a recent user submitted issue. I put this down to a later version being included with the VS Installer than on the Marketplace.
