I’m developing an app for WP7, but I ran into a problem I haven’t seen before. When I build and run it in the emulator, it works as it should both in debug, and no-debug (ctrl-F5). But on the Windows device, it’s only working in debug (F5). When i run it on the device without debugging (ctrl-F5), the app starts, but when I get to a button-click, it just exit the app. In the button-click, I load an xml file. The xml file is set to Build Action “Content”, Copy to output “Do not copy”. Am I doing something wrong? I’m wondering if the following code in the xaml file beeing loaded has something to do with the error:

And the MainViewModel:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using appname.Helpers;
namespace appname
{
public class MainViewModel
{
public MainViewModel()
{
App app = Application.Current as App;
XmlHelper xmlHelper = new XmlHelper();
app.persons = xmlHelper.GetPersons(app.gender);
List<Person> persons = app.persons;
this.Persons = new LongListCollection<Person,char>(persons, person => person.Name[0]);
}
public LongListCollection<Person, char> Persons
{
get;
private set;
}
}
}
Edit
The code for the xml file-reading:
public List<Person> GetPersons(string gender)
{
string xmlPath = "";
if (gender == "Boys")
xmlPath = @"Resources/Boys/Xml/Names.xml";
else if( gender == "Girls" )
xmlPath = @"Resources/Girls/Xml/Names.xml";
//Uri uri = new Uri(xmlPath, UriKind.Relative);
StreamResourceInfo sm = Application.GetResourceStream(new Uri(xmlPath, UriKind.Relative));
System.Xml.XmlReader xr = System.Xml.XmlReader.Create(sm.Stream);
XDocument data = XDocument.Load(xr);
return (from c in data.Descendants("Person")
orderby c.Attribute("Name")
select new Person()
{
Name = c.Element("Name").Value,
Description = c.Element("Description").Value,
...
HasGraph = c.Element("HasGraph").Value
}).ToList();
}

Oh my god
I tried starting another app on my phone, and it exited also. So, I rebooted the phone (thought I had done this yesterday..), and it works! I’m sorry for wasting your time!
Regards an embarrased fool!
