I want to open a WPF Window from a Console application. After referring to this post, it works fine.
The problem is: When the user closed the WPF Window (manually), it can no long be re-opened from the Console, throwing the exception message: "Cannot create more than one System.Windows.Application instance in the same AppDomain."
Here is the code:
class Program
{
static void Main(string[] args)
{
string input=null;
while ((input = Console.ReadLine()) == "y")
{
//Works fine at the first iteration,
//But failed at the second iteration.
StartWpfThread();
}
}
private static void OpenWindow()
{
//Exception(Cannot create more than one System.Windows.Application instance in the same AppDomain.)
//is thrown at the second iteration.
var app = new System.Windows.Application();
var window = new System.Windows.Window();
app.Run(window);
//User closes the opened window manually.
}
private static void StartWpfThread()
{
var thread = new Thread(() =>
{
OpenWindow();
});
thread.SetApartmentState(ApartmentState.STA);
thread.IsBackground = false;
thread.Start();
}
}
How can I re-open the WPF Window?
