I have a WPF window containing a RadWebCam control and a CameraSettingsControl control associated with it (as shown in the online documentation). When I close the WPF window, no memory associated with that window is released. I implemented a Finalizer in the window and found that it wasn't getting called even after several GC.Collect() calls. The culprit appears to be the CameraSettingsControl when it's associated with the RadWebCam control. In my application, it's not freeing about 80MB of memory after each window invocation.
I have included a full project sample which demonstrates the issue. Just set a BreakPoint on the finalizer ~TakePicture(). When the application is run, hit the 'Take Picture' button to launch the Camera window, and then close it. To verify that it's not just a delay in garbage collection, hit the GCCollect button on the main window a couple of times. The Finalizer never gets called until you exit the app.
Here's the Telerik control WPF I'm using, but it's also in the sample.
