Windows Phone 8 Connection Handler / Internet Availability - windows-phone-8

Question

My team is working on a team project aplication. At the moment, we need an event handler to check the connection status (if it's on/off).
I had big hopes in the System.Net.NetworkInformation Namespace, but unfortunately most important things aren't supported in wp8.
Can anyone help me with it a bit?
Edit 1#
It seems, I didn't specifed my problem well.
I'm using Mvvm light expresion, and it does not support that namespace or at least I can't add it.
I'm a newbie in using VS and c# atm, mayby I'm doing someting wrong, but simply when im trying to add the refernce to my project it does not list.

Answer 1

I haven't tried the System.Net.NetworkInformation namespace on WP8. But the new WP8 Windows.Networking.Connectivity Windows Phone Runtime namespace works just fine.
Use Windows.Networking.Connectivity.NetworkInformation.NetworkStatusChanged to know when network conditions change and use Microsoft.Phone.Net.NetworkInformation.NetworkInterface properties or Windows.Networking.Connectivity.NetworkInformation properties to see what's up.
private async void MainPage_Loaded(object sender, RoutedEventArgs e)
{
PrintNetworkStatus();
NetworkInformation.NetworkStatusChanged += NetworkInformation_NetworkStatusChanged;
}
void NetworkInformation_NetworkStatusChanged(object sender)
{
PrintNetworkStatus();
}
private void PrintNetworkStatus()
{
Dispatcher.BeginInvoke(() =>
MessageBox.Show(NetworkInterface.NetworkInterfaceType +
Environment.NewLine +
NetworkInterface.GetIsNetworkAvailable()));
}
When I test this code snippet on my WP8 Lumia 920 it works as expected. On startup when my phone is on WiFi only I see the following MessageBox:
And once I shutdown my WiFI router and the WiFi connection on the phone is lost I see the following MessageBox:

Try this:
bool isNetwork=NetworkInterface.GetIsNetworkAvailable();
if(!isNetwork)
{
//proceed with your code
}

Answer 3

In App.xaml.cs, create a property like below
/// <summary>
/// check if network is available
/// </summary>
public bool IsNetworkAvailable
{
get
{
return NetworkInterface.NetworkInterfaceType != NetworkInterfaceType.None;
}
}
And you can use this property anywhere in your project as in below code
if (((App) Application.Current).IsNetworkAvailable)
{
//Lines of Code
}
else
{
MessageBox.Show("Not Connected to Network!", "Checking Connection!",
MessageBoxButton.OK);
}
