By following the instructions provided there, I downloaded the 2.65 binary file and copied to my nopcommerce plugin directory under newly created sub directory called "Payments.SagePayServer". After that, I build the solution, ran the application, reloaded the plugins from the Configuration / Plugins menu. But still I can not find the Payments.SagePayServer under my plugins list.
yes Renzo. I have copied the description.txt file too. I even tried to download the source code and try to add it as project. the project build successfully. but the result is still same.
