Simple WPF sample causes uncontrolled memory growth

Question

I have boiled down an issue I\'m seeing in one of my applications to an incredibly simple reproduction sample. I need to know if there\'s something amiss or something I\'m missi

Answer 1

WPF in .NET 3 and 3.5 has an internal memory leak. It only triggers under certain situations. We could never figure out exactly what triggers it, but we had it in our app. Apparently it's fixed in .NET 4.

I think it's the same as the one mentioned in this blog post

At any rate, putting the following code in the App.xaml.cs constructor solved it for us

public partial class App : Application
{
   public App() 
   { 
       new HwndSource(new HwndSourceParameters()); 
   } 
}

If nothing else solves it, try that and see
