i had download the nopCommerce 3.80 - Source code (101 MB) and install and configure the nopcommerce after that direct add website at IIS.
Hi Vijay,
Source code: if you want to customization then you can open it on visual studio and do your customization. Once you done it, then have to publish Nop.Web, which will be your deployable code, that you can configure on hosting server/iis
No source: Ready-mate published code of default nopCommerce, which you can configure directly on hosting server/iis
