Hmm.. a short night's sleep seems to have changed the mood of my devices
somehow. Now they connect to https://www.google.com with my code
(unchanged).
But it's still a nogo for my internal service. The internal service provides
an actual web interface (automated help provided by WCF), which is
accessible from the phone's browser (after the usual certificate warning),
so I suppose WCF services do something different in connection establishment
that mono cannot handle.
Since I cannot make the internal service publicly accessible, I wonder what
would help trace down the problem.
I went ahead installed mono 4 windows and created a simple program. After
the usual "hey, this works with Microsoft.Net but won't even compile in
Xamarin Studio" confusion, I came up with this (see end of mail). It works
if I run it with Microsoft.Net, and it throws a pretty similar error (see
very end of mail) running it with Mono, thus confirming that the problem
lies indeed with Mono's handling of the encrypted request.
I guess I have no choice but to write a repro server project (which has to
be run on windows running microsoft's .net runtime)
