Is there a difference between is and Type.IsAssignableFrom?

Question

C++ / C#

Hello. Is is sugar under the hood doing Type.IsAssignableFrom ?

Answer 1

No, it's not the same thing.
the is operator under the hood calls the isinst IL instruction
AND it works with object instances.

Test if obj is an instance of class, returning null or an instance of that class or interface.

And Type.IsAssignableFrom - works with an instance of Type, and does a lot of complex checks:
