• GitHub Extension for Visual Studio version: 2.5.1.2234
• Visual Studio version: Microsoft Visual Studio Enterprise 2017 Version 15.6.6

Each time that I load a solution under a git repo, I'm getting the following message:

[sebastianferrari]

It has been solved after installed the latest VS v15.6.7

[Mike-E-angelo]

I am getting this after installing 15.8.1

[Calabonga]

Visual Studio 15.8.1
me getting too...

[rjgotten]

Same problem with 15.8.1 here as well.
Any way to just flat out uninstall the entire package and not get it back?

Not like I'm even using this.

[Sholofly]

Updating the GitHub extension to the latest version (2.5.5.3913) seems to solve the issue.

[softlion]

It's back !!

Hi,

The dialog was asking continue to show the error msg? What if I clicked no? would that continue show the error msg when next load?

I did some fix, but I m not sure if the fix was done. or could some let me know how this error would affect the github extension?
