Hi! I've been a longtime c#.net programmer at a corporate office. I've been wanting to do some side work though, and I would love for it to grow to fulltime freelance. Problem is that most of my work has been intranet applications that are functionally sound but not very pretty. I've always considered myself a developer of systems with web interfaces, rather than a true web developer. My front-end experience is WinForms, ASP.NET MVC, and Blazor.
Is it worth learning the popular frameworks like WPF and React? Any resources out there on how to make web/apps that look pretty and good UI design? Appreciate the help
