IDEA for C#

Hi,

at the moment I am developing some programs in java and C# (exactly the same
functionality). I thought of creating a special filetype for that purpose.
As the java language is very similar to C# is there a chance to copy the
definition from the java filetype to the newly created filetype (and then
replacing the keywords that differ, e.g. import --> using)? I already tried
to figure out in which jar the corresponding xml file is stored but hat no
success yet. Any help appreciated...

Best regards,
