[Gtk-sharp-list] BadImageFormatException : format file invalid

[Ivan]

Hi,

(1) When I run test.exe (compiled with csc) with NPlot.Gtk.dll
(compiled with csc), it works fine.

(2) When I run test.exe (compiled with mcs) with NPlot.Gtk.dll
(compiled with csc), I got this error.

Unhandled Exception: System.BadImageFormatException: The format of the file 'NPl
ot.Gtk' is invalid.
File name: "NPlot.Gtk"
   at X.Main()

(3) When I run test.exe (compiled with csc) with NPlot.Gtk.dll
(compiled with msc), I got the same error.

(4) When I run test.exe (compiled with mcs) with NPlot.Gtk.dll
(compiled with msc), I got the same error.

Anyone knows what can cause this error to happen?
Currently I suspect I need to include application configuration
(test.exe.config). But how?

Ivan.
