I have seen similar question regarding installing other NuGet packages. But nothing for "System.Security.Cryptography.Algorithms 4.3.0", so please forgive me if this question seems repeated to you. I'm new to Xamarin, so I may ask questions that seem obvious to you.
I need the above mentioned package for PCL, and I know on .iOS, or .Droid projects, using 'System' namespace provides all the cryptography stuff you need, but I don't want to have repeated codes in those two projects. So I thought the best strategy would be to get the mentioned NuGet package, but it is not installed and gives me the following error:
Could not install package 'System.Security.Cryptography.Algorithms 4.3.0'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.6,Profile=Profile44', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
p.s. I use Xamarin Studio on Mac
Many thanks for your help in advance.
