I have been reading all over the internet trying to find out how to code SharePoint 2013 online. I wanted to be able to make Visual Web Parts but after going down that road, I now read that Microsoft shut off Sandboxed Solutions ? Can anyone give me a clear explanation of how to code C# in SharePoint 2013 online ?
With C# I can do anything, connect to azure databases, sharepoint lists, take over the DOM and make my own pages etc etc etc. Is there still a way to do all the things I could do with C#. If C# is indeed no longer allowed, what do you use ?
