Why no IDisposable in wpf ?

[trebahl]

I understand that individual controls don't have a window handle, so they don't need a Dispose method. However, there are still a couple classes that need to have resources explicitly freed, like Window and DispatcherTimer. For these classes, we have to call a method with some random name (Close, Stop, ...). Making them IDisposable would advertise that fact and uniformize the handling from client code.

• DispatcherTimer should implement the IDisposable interface #8839
• Known issue: WPF will throw COM Exception when create RenderTargetBitmap too fast #3067
