Hi fastofruto,

Take a look at A Perl Hacker's Foray into .NET over at www.perl.com.
There is a section titled Perl and .NET, which may be of interest to you.

Update: A Super Search on this topic returns Perl compiler for .NET - anyone knows anything about it?, Jenda's reply should help you. Also I google'd this topic after posting which returns the following c# code for calling a Perl scrpt:

ProcessStartInfo ps = new ProcessStartInfo("perl.exe", "program.pl arg
+s");
ps.UseShellExecute = false;
ps.RedirectStandardOutput = true;
Process p=new Process();
p.Start(ps);
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();

Hope this helps
