Generic Object Storage Helper for WinRT

[TestMethod]
public async Task SaveObject()
{
  //Instantiate an object that we want to save
  var myPoco = new Poco() { IntProp = 1, StringProp = "one" };
  //new up ObjectStorageHelper specifying that we want to interact with the Local storage folder
  var objectStorageHelper = new ObjectStorageHelper<Poco>(StorageType.Local);
  //Save the object (via XML Serialization) to the specified folder, asynchronously
  await objectStorageHelper.SaveAsync(myPoco);
}

[TestMethod]
public async void LoadObject()
{
  //new up ObjectStorageHelper specifying that we want to interact with the Local storage folder
  var objectStorageHelper = new ObjectStorageHelper<Poco>(StorageType.Local);
  //Get the object from the storage folder
  Poco myPoco = await objectStorageHelper.LoadAsync();
}

[TestMethod]
public async Task SaveAndLoadTwoObjectsOfSameTypeUsingDifferentHandles()
{
    //Declare two instances of the same type. Notice how we only have one instance of ObjectStorageHelper<T>
    var poco = new Poco() { IntProp = 1, StringProp = "one" };
    var anotherPoco = new Poco() { IntProp = 2, StringProp = "two" };
    var osh = new ObjectStorageHelper<Poco>(StorageType.Local);

    //Store them both then retrieve them both. In each case, use a different handle.
    await osh.SaveAsync(poco, handle);
    await osh.SaveAsync(anotherPoco, handle2);
    var result = await osh.LoadAsync(handle);
    var anotherResult = await osh.LoadAsync(handle2);

    //Check that the second call to SaveASync() did not overwrite the object saved by first call to SaveAsync()
    Assert.AreEqual(poco, result);
    Assert.AreEqual(anotherPoco, anotherResult);
