Does .NET have a native support for getting input from webcam?
If not, what is the best/recommended way to get input from webcam using C#/.NET?

A webcam is an input device that captures digital images. These are transferred to the computer, which moves them to a server. From there, they can be transmitted to the hosting page. Laptops and desktops are often equipped with a webcam.
A webcam is an input device because it captures a video image of the scene in front of it. It is either built in to the computer (e.g. laptop) or it is connected through an USB cable. The video signal is made up of a series of individual 'image frames' which are an instant snapshot of the scene in front of it.
Steps to capture a video:Use cv2. VideoCapture( ) to get a video capture object for the camera. Set up an infinite while loop and use the read() method to read the frames using the above created object. Use cv2.
.NET does not have a native support for webcams. You can use OpenCV library. Also a .NET wrapper exists for OpenCV - Emgu CV.

On the other hand, the "native" option is to develop this using DirectShow. However, there is no (as far as I know), official managed interface for DirectShow, so it can have a steep learning curve to develop with.
