This happens at least once a day, without visibly interfering with any other aspect of the packages facet of this project. When I enter an install-package
command, this is the package manager's response in the console:
PM> Install-Package UmbracoCms
Invoke must be called on a background thread.
GET https://api.nuget.org/v3/registration1-gz/umbracocms/index.json
OK https://api.nuget.org/v3/registration1-gz/umbracocms/index.json 306ms
GET https://api.nuget.org/v3/registration1-gz/umbracocms/page/7.6.0/7.6.3.json
All else seems to work fine, most of the time, after that. I have a fair suspicion that the installation of the dotnet and nuget CLIs may have played a role.
