I'm trying to make custom web parts for my SharePoint site through Visual Studio 2015, but I keep getting the error below.
Is there a way for me to develop custom web parts without having SharePoint Server 2013 installed? I may not be able to get SharePoint server since my web site is on the SharePoint server run by another department. I do have full control to customize the SharePoint site, but I would like to be able to make custom web parts for full functionality. Also, I don't know if my current computer specifications can handle SharePoint Server 2013.
If I do require SharePoint Server 2013, would I still be able to develop custom web parts if my website is on a SharePoint server that is not on the same computer I'm developing the web parts?
