description: In the method:
private DatabaseParameterBuffer BuildDpb(IDatabase db, FbConnectionString options)
line +- 538, dpb.Append(IscCodes.isc_dpb_process_name, Process.GetCurrentProcess().MainModule.FileName);

Generates a security exception and you can not connect.
I wrapped it in a try catch block and is working now.

#⁠if (NET_CF)
// for CF we can implement GetModuleFileName from coredll
#⁠else
try
{
dpb.Append(IscCodes.isc_dpb_process_name, Process.GetCurrentProcess().MainModule.FileName);
}
catch(Exception)
{
dpb.Append(IscCodes.isc_dpb_process_name, "Probably IIS");
}
#⁠endif

A website setup in IIS with "Anonymous Authentication" and "http://ASP.NET Impersonation" using the .Net provider generates the following error when connecting.
