Can you try dotnet --info in Console, and paste the output?

Thanks @sdwheeler for the details.

Can you open folder %USERPROFILE%\.vscode\extensions\docsmsft.docs-preview-0.3.16\.markdocs, and check if Newtonsoft.Json.dll exists in current folder? If it exists, can you try run command dotnet MarkdocsService.dll under current folder and check if same issue occurs?

If same issue still occurs, can you help to install .NET Core SDK v2.0.0 from here and try it again? It would be helpful to identify the root cause.

It turns out Newtonsoft.Json.dll is missing from the folder, maybe a network issue occurs while downloading the dependency.

Reinstall docs-preview should resolve this issue. Can you have a try?

[sdwheeler]

Ok, removing and reinstalling the entire Docs Authoring Pack fixed it.
