Body

Description:

Upon opening Visual Studio with the extension installed and loading any project, I got an error dialog similar to this:

Except the package that failed to load was the 'ConversationsPackage', not the 'CSharpPackage'.

Then upon inspecting %AppData%\Microsoft\VisualStudio\17.0_014effd0\ActivityLog.xml as suggested, I found the following near the bottom of the log:

SetSite failed for package [ConversationsPackage]Source: 'StreamJsonRpc' Description: Object reference not set to an instance of an object.

Steps to reproduce:

Simply install the GitHub Copilot extension from the Extensions -> Manage Extensions menu and reload VS.

Expected behavior:

Extension loads without error.

N.B: I have uninstalled the extension and reinstalled it by manually downloading the *.vsix file from Visual Studio Marketplace after signing up for the Copilot X beta program, and this seems to have actually worked! Very strange...but this is why I could not give a screenshot of the actual error dialog that pops up.

Hi @kenny1983 ,

GitHub Copilot is currently only available for 64-bit versions of Windows, macOS, and Linux. It is not currently supported on ARM-based processors, including ARM 64-bit processors.

If you are running Visual Studio Enterprise 2022 on an ARM 64-bit processor, you will not be able to use the GitHub Copilot extension at this time. Please check out this documentation for more details.
