All,
I have just updated the .Net framework to 4.5 and re-installed Microsoft.CSharp (as it was showing a yellow icon next to it under my reference folder).
Now every time I try to install or update ANY package from Nuget, I get the following error in red:
An error occurred while retrieving package metadata for 'Microsoft.CSharp.4.3.0'
I also tried to update the Nuget Package Sources to the following at different time but to no avail: https://www.nuget.org/api/v2/ http://packages.nuget.org/v1/FeedService.svc
Can anyone shed some light on the above?
