Since this code is unreachable, the enclosing try/finally serves no purpose other than whatever RuntimeHelpers.PrepareConstrainedRegions does. I have preserved the try/finally (by adding it in .net core) but I suspect it can be removed, because according to the documentation (emphasis mine):

The PrepareConstrainedRegions method must immediately precede a try block and marks catch, finally, and fault blocks as constrained execution regions.

If I understand correctly, RuntimeHelpers.PrepareConstrainedRegions only affects catch/finally and has no effect if they are empty.
