Hi,

I'm entirely new to mono so I'd really appreciate help with the following.
I am trying to run OpenVista CIS, which is supposed to run with mono under
Linux, on Ubuntu 11.10. I get the following errors:

mfleming at mgf-desktop:~/openvista/openvistacis-0.9.96-client$
./OpenVistaCIS.exe
Missing method System.Reflection.Assembly::op_Equality(Assembly,Assembly)
in assembly /usr/lib/mono/2.0/mscorlib.dll, referenced in assembly
/usr/lib/mono/gac/gdk-sharp/2.12.0.0__35e10195dab3c99f/gdk-sharp.dll
---Initial Exception---
Method not found: 'System.Reflection.Assembly.op_Equality'.
  at Medsphere.OpenVista.CIS.OVMain.Run (System.String[] args) [0x00000] in
<filename unknown>:0
  at Medsphere.OpenVista.CIS.OVMain.Main (System.String[] args) [0x00000]
in <filename unknown>:0

---Second Exception---
An exception was thrown by the type initializer for Nest
  at Medsphere.OpenVista.CIS.OVMain.ShowUnhandledException
(System.Exception ex) [0x00000] in <filename unknown>:0
[ERROR] FATAL UNHANDLED EXCEPTION: System.MissingMethodException: Method
not found: 'System.Reflection.Assembly.op_Equality'.
  at Medsphere.OpenVista.CIS.OVMain.Run (System.String[] args) [0x00000] in
<filename unknown>:0
  at Medsphere.OpenVista.CIS.OVMain.Main (System.String[] args) [0x00000]
in <filename unknown>:0

It appears to me that this is probably a problem with the way mono is
configured in this Ubuntu distro, but I have no idea how to fix it. Any
assistance would be greatly appreciated.
