What is the best way to capture video in a WPF application? I am looking for a way to detect the video devices, and then capture video from the selected one.
There is no WPF support for this. You need to use the traditional, expected windows APIs for video capture, such as DXVA.
If you are OK with using ActiveX controls in WPF app, you can use VideoCapX from http://www.fathsoft.com/videocapx.html

is it possible to create a permanent notification at the notification bar in Windows 10?
Also it is necessary to do this in a windows form application and not an universal windows app.
Thanks for you help.
To do it in a WinForms app you'll need to use the desktop bridge to create the notifications.
It's not possible to have a toast that can't be dismissed from the action centre (which is what I assume you mean by "notifications area") but you can detect when it's removed and then add another back in. There are already a number of apps which do this as a way of having "permanent notifications".

I'm looking for a way to make a WPF window stay on top of a fullscreen UWP app. I found numerous mentions of Window.Topmost, but it only works with a windowed app.
For a little bit of context, the idea is to create a virtual keyboard that I could launch from the app (with a brokered runtime component). I do know that there are some keyboard implementations, but they don't do the trick since they basically edit the textboxes themselves (and I need it to be able to also interact with WebViews).
Thanks :)

I am learning C# and I want to create a countdown timer application that displays the time in a digital format on an image of a stopwatch and gives verbal time updates at certain times.
How do I go about displaying images to the screen and playing sound? I have used pygame in python to achieve this so basically I am looking for suggestions for something similar in C#.
I hope this makes sense! Thanks.
The best technology to use for that would probably be Windows Presentation Foundation (WPF).
Here's an example of an application made in WPF similar to what you want to do:

I am creating a program that displays song lyrics using WPF. I want to use videos as the background(using VLC player). How can I overlay the lyrics over the video background?
Thanks in advance.
This may not be possible directly in WPF. I assume that you would need a WinformsHost to host the VLC player. It's a known issue(limitation) that WPF controls and winforms can't share the same screen area(airspace limitation). However there are many workarounds for this limitation, one of them being adding 2 WPF windows overlayed.
Alternatively you can try upgrading to WPF 4.5(Using VS-2012), this issue seems to b e fixed there.

I want to create a asp web application for video conferencing, how i can implement this?
Thanks...
In my point of view, the better support for such issue was implemented within Silverlight technology. As start point I can suggest: http://msdn.microsoft.com/en-us/library/ff602282%28v=VS.95%29.aspx
It is possible to implement your Silverlight into ASP.NET like was described here
