I've been searching all over and I did see a couple of C# samples for C#, but they all seem to rely on getting a layer from an entity.

I need to just turn a layer's visibility on and off, and I don't see anything like this, and the documentation is really sparse on this.  I see in C# there is a LayerManager and LayerManagerClass - but everything I try seems to error.

Granted I'm a newbie to C#, so if I looked right at it, please point me in the right direction....

TIA.
