Description
Describe the problem this feature would solve
The ObjectStorage helper interfaces and implementations currently live in the *.Uwp package. This means that they are not consumable from NetStandard code.
Describe the solution
I propose we migrate the IObjectSerializer,IObjectStorageHelper, and SystemSerializer interfaces/classes up to the *.Toolkit package, which is NetStandard. There will need to be a few modifications to remove the Windows.Storage namespace, but very minor.
I'm working on a new Graph powered implementation that I think would work nicely with the existing setup in WCT. However, I don't want to take the dependency on Windows to do so. It isn't needed, so this change will enable more flexibility in storage helper implementations.
Describe alternatives you've considered
I could NOT extend the IObjectStorageHelper, but we would lose the ability to easily swap with the existing/deprecated RoamingObjectStorageHelper.
OR
I could leave the StorageHelper interfaces where they are and take the Windows dependency, but that would prevent any NetStandard projects from taking advantage of the new Graph powered implementations.
