Description

Using this Visual C# WPF application source code you will learn how to develop a camera viewer in C# that allows you to display the image of your USB webcam and to stream the camera image to remote PCs and smartphones. Instead of presenting a long article, I would rather show how to implement such application with a few lines of C# code by using the prewritten components of a C# camera library (www.camera-sdk.com).
