I am re-phrasing your question to be;
"are there things that .NET Framework/.NET core can do that TCC/TCMD cannot do?"
TCC/TCMD use a third-party tool as an interface to PowerShell
Ref:
PShell @
PShell
The third-party tool that provides an interface to PowerShell only accommodates version 5.1
The tool does
not provide an interface to version 7.
TCC/TCMD relies on the Windows API to accomplish tasks.
TCC/TCMD cannot directly interface to .NET Framework/.NET core.
An attempt was made to create a
plugin for TCC/TCMD using C#,
but no further progress has been made.
If you can write programs in C++ or PureBasic,
you can write a
plugin for TCC/TCMD,
which would allow you to do low-level work just like PowerShell,
except you will be only able to use the Windows API, not .NET
