What library can you recommend to capture image from a webcam in .Net?

A:
Windows Image Acquisition does the trick with wiaCommandTakePicture (VB.NET as per your tag :) )
as demonstrated in this project by Hanselman in coding4fun
I pasted the C# code, but you can read the VB.NET alternatives on the site also:
CommonDialogClass class1 = new CommonDialogClass();
Device d = class1.ShowSelectDevice(WiaDeviceType.UnspecifiedDeviceType, true,false);
if (d != null)
{
settings.DeviceID = d.DeviceID;
settings.Save();
}
Item item = device.ExecuteCommand(CommandID.wiaCommandTakePicture);
foreach (string format in item.Formats)
{
if (format == jpegGuid)
{
WIA.ImageFile imagefile = item.Transfer(format) as WIA.ImageFile;
filename = GetFreeFileName();
if (string.IsNullOrEmpty(filename) == false)
{
imagefile.SaveFile(filename);
}
this.picLastImage.Load(filename);
return filename;
}
}
