I was wondering, is it possible to develop web parts etc. for SharePoint Online with .Net / C# through Visual Studio 2019?

Answer 1

The only method for SharePoint Online with C# is to build a SharePoint Provider Hosted addin. SPFx is built using JavaScript/TypeScript rather than C#.

Answer 2

Yes, you can through SPFx development model.

The SharePoint Framework (SPFx) is a page and web part model that provides full support for client-side SharePoint development, easy integration with SharePoint data, and extending Microsoft Teams. With the SharePoint Framework, you can use modern web technologies and tools in your preferred development environment to build productive experiences and apps that are responsive and mobile-ready.
