Version of SDK

latest (NuGet 3.0.0)

Issue

Any instance of TableCell is defaulted to Container instead of TableCell. Due to this, any Adaptive Cards which contain a non-empty Table are unable to be rendered.

Trying to render the card on Microsoft Teams sends a "Bad Request"

Original reference & workaround is here

Steps to Reproduce

Try to render an Adaptive Card v1.5 with a non-empty Table i.e. with a row with a non-empty TableCell value will throw an error when it is being rendered on Microsoft Teams. This makes Adaptive Cards 1.5 with Table Support unusable for anyone using the .NET SDK who don't know the workaround.

When can we expect an update on the NuGet package?
The retirement of Office 365 connectors will probably result in a lot of new users of this package.
Fixing this bug would make the migration a bit easier, it already took me some time before I figured out what the issue was.
