Today, we have checked this issue with:

XS 4.2.3(build 154)- 4dca4a28d7ecc2c4df8a4d58e74b8902d0283b53
Xamarin addins:cc120a6f639fa6649aa4d23a0f0e7c5701134047
ML 10.8.5

Now this issue is not exist, we are successfully able to set breakpoint on System.Console.WriteLine in Console application without any Exception.
