Appears on Lumia 800.

Callstack: System.IO.IsolatedStorage.IsolatedStorageException occurred Message=An error occurred while accessing IsolatedStorage.

Checked my test project (that kinda works) with debugger. _lastAccessTimeDictionary contains 0 as values (last access time). Can you check that on your side?

Another think is that exception is not catched there. Probably, because using is inside of try-cath. But i'm not sure.

I have not got wp7 phone or sdk. MSDN says that IsolatedStorageException could occur when The isolated store has been removed. -or- Isolated storage is disabled.

IsolatedStorageFile.GetLastAccessTime

Can you check property IsolatedStorageFile.IsEnabled?

Actually, whole process is looking a bit strange. I always used it like

using (var isoFiles = IsolatedStorageFile.GetUserStoreForApplication())

You're using just IsolatedStorageFile, and it works :) Also, there's no ISF.IsEnabled. I'm using it in

using (var file = ISF.OpenFile(fullCacheFilePath, FileMode.Open, FileAccess.Read)) { cacheSizeInBytes += file.Length;

                        var t = ISF.GetLastAccessTime(cacheFileName).Millisecond;

                        var b = ISF. // IsEnabled is not here

                        JetImageLoader.Log("Size of " + cacheFileName + " is " + t);

                        _lastAccessTimeDictionary.Add(fullCacheFilePath,
                            ISF.GetLastAccessTime(cacheFileName).Millisecond);
                    }

You can close this either :)
