Description Brian 2015-12-01 14:53:04 UTC

If I try to compile the below statement under Mono 4.2.1: 

var x = (myObject?.MyChildObject is ISomeInterface) ? 1 : 0;

I get the following error:

error CS0266: Cannot implicitly convert type `bool?' to `bool'. An explicit conversion exists (are you missing a cast?)

On MS .NET this compiles fine
