I just wanted to know about, how to change the PCL profile in Xamarin with Visual Studio 2015 Update 2. While installing some of the package, I am getting an error that, this package is not compatible with the PCL profile 259.
Thank You in advance.
Right-click on the PCL project and select Properties. Then, in the "Library" tab, select the "Change..." button under the Targeting section.
Select the targets you want which match the profile you want.
