[Mono-list] Mono on ARM Chromebook

[Hall72215]

I have installed ChrUbuntu on my new ARM Chromebook, and was interested in
running a .NET WinForms app (KeyPass).  So, I did "apt-get install
mono-complete" and tried to run it, but it crashes.  To make sure that mono
wasn't completely broken, I made a program that just wrote "Success" to the
console, and it worked.  Next, I made a "hello world" winforms app (just a
form with a button), compiled it, and ran it.  It crashed with the exact
same error as KeyPass.  So then I ran "mono --version", and saw that the
architecture said armel.  The Chromebook is armhf, so I thought all I needed
to do was download the source and compile it myself.  But then I found out
that hard float ARM isn't supported yet.  Can I assume that the architecture
mismatch is the problem?  Any idea on when armhf will be supported?

Here's the top of the stack trace:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates a fatal
error in the mono runtime or one of the native libraries used by your
application.
