Web Server

EmbedIO is a tiny embeddable C# web server, that I tried out a while back. It was easy to embed it in a Windows Forms application, and I even added a web browser window using CefSharp, which I then used to display the HTML, JavaScript and CSS content that was served from EmbedIO. If you need a tiny web server or REST API, that can be embedded in a Windows Forms, or WPF application, then EmbedIO might be worth a try.

They list some potential use cases on their GitHub page:

• Write a cross-platform GUI entirely in CSS/HTML/JS
• Write a game using Babylon.js and make EmbedIO your serve your code and assets
• Create GUIs for Windows services or Linux daemons
• Works well with LiteLib – add SQLite support in minutes!
• Write client applications with real-time communication between them
