Description
The IsType function in the Dataverse Accelerator implementation of the PowerFx runtime does not yet support IsType (returns the error "IsType is a known but not supported function").
This is an issue because AsType on its own is not failure-safe, so the low code plugins cannot safely handle polymorphic attributes.
I'm willing to help implement this capability with my own Open-Source contributions, just looking for guidance on where to contribute as well as any implementation guidelines the FT team has to offer.

Research direction
Start by locating the Dataverse Accelerator PowerFx runtime implementation and examining how AsType and unsupported functions are handled. The work is done when IsType is supported instead of returning the known-but-not-supported error and low code plugins can safely handle polymorphic attributes.
