Code works fine in a Windows Form application, but fails on Mono for Android.

Attached code.

There is neither a repro project nor even description on the "web service" he is referring, so it's all guess, but unless there is some special library that handles SPNEGO, it is part of WS-Security stack in WCF that we never supported. It does not work and won't work unless someone in mono community implements WS-Security in WCF core stack AND WCF in MfA is extensively expanded to cover that API, which is very unlikely to happen.
