Application.Current.Shutdown(); is defined in an assembly not referenced

c#, visual-studio-2010, wpf

Solution

Well ok, I guess your issue is solved when you add System.Xaml.dll as reference to your project. The interface is declared there. Here is the doc.

Problem

I'm getting the error: Error 1 The type 'System.Windows.Markup.IQueryAmbient' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Xaml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. When doing the following: ``` public void ExitApplication() { Application.Current.Shutdown(); } ``` The project is targeted to .NET 4.0, my Visual Studio is 2010, I tried adding `using System.Windows.Markup;` with no succes, and `using System.Xaml;` where Xaml doesn't exist in namespace System. What should I do to fix this?
