You can use ApplicationData.Current.LocalSettings;
Sample Code:
Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
// Create a simple setting
localSettings.Values["exampleSetting"] = "Hello Windows";
// Read data from a simple setting
Object value = localSettings.Values["exampleSetting"];
if (value == null)
{
// No data
}
else
{
// Access data in value
}
// Delete a simple setting
localSettings.Values.Remove("exampleSetting");
& here is relevant post from MSDN
Apart from this you can try this from CodePlex [I didn't tried this before]
