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
Fixed in master
Awesome, thanks for the quick response!
