On returning from Tombstone, the data in IsolatedStorageSettings.ApplicationSettings is gone.
Any advice or suggestion would be greatly appreciated. Thanks.
Details:
When I try to save into IsolatedStorageSettings.ApplicationSettings a dictionary that maps STRING keys to OBJECT values, after returning from tombstone, all the values from the isolated storage are gone. If I don't try to save that dictionary, there are no problems when returning from Tombstone.
Here is the code:
[DataContract]
[KnownType(typeof(TestClass))]
public class TestClass
{
[DataMember]
public string Property1 { get; private set; }
public TestClass(string prop1)
{
Property1 = prop1;
}
}
public static void AddValuesToIsolatedStorage()
{
IsolatedStorageSettings.ApplicationSettings["Key1"] = 1234;
IsolatedStorageSettings.ApplicationSettings["Key2"] = "abcd";
Dictionary<string, object> dict = new Dictionary<string, object>();
dict.Add("the key", new TestClass("a"));
// IsolatedStorageSettings.ApplicationSettings["Key3"] = dict;
// IsolatedStorageSettings.ApplicationSettings.Save();
}
What I observed (both on the emulator and on my phone - HTC HD7) is that if the 2 lines remain commented out, when I return from Tombstone, IsolatedStorageSettings.ApplicationSettings.Count returns 2 (expected), and both Key1 and Key2 are present.
However, if I uncomment the two lines, upon returning from tombstone, IsolatedStorageSettings.ApplicationSettings.Count returns 0, and neither Key1, nor Key2, nor Key3 are in IsolatedStorageSettings.ApplicationSettings.
Expected: with the two lines uncommented, on returning from tombstone, IsolatedStorageSettings.ApplicationSettings.Count would return 3, and Key1, Key2, and Key3 would be present.
