### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

The .NET implementation of the manifest, context, encryption device, could be leaking memory like the ballots did. This was due to the Handle to the C++ structures were getting closed before they were calling the code for Freeing the memory.

The rest of the classes should be looked at to make sure if they are leaking or not.
