I have created a visual web part using visual studio of type "Farm solution", then I add the wsp file using the following command:-
PS C:\Users\Administrator> Add-SPSolution c:\RedirectManagedMetaData.wsp
after that this solution appeared under the "CA>>System Setting>>Manage Farm Solutions", as follow:-
now from the central administration I only have the option to deploy it to web application/s level, while in my case I only need this wsp solution to be inside single site collection and not to all site collections within my web application. So is there a way to deploy a farm solution to specific site collection/s?
