I have the console opened at the bottom and inside i type:
Install-Package OpenPop.NET that's what they say to type in the website:
I typed it in the console but i'm getting error:
Install-Package : The current environment doesn't have a solution open. At line:1 char:1 + Install-Package OpenPop.NET + ~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [Install-Package], InvalidOperationException + FullyQualifiedErrorId : NuGetNoActiveSolution,NuGet.PowerShell.Commands.InstallPackageCommand
Do i need to download something else ?
The current environment doesn't have a solution open.
You must start with a solution to add a package to it. You add NuGet packages to solutions, not Visual Studio.
