I'm actually working on a project where I need to host a .NET webservice on a linux server hosting a firebird database. When I try to run the sample code from http://www.mono-project.com/Firebird_Interbase and call the method, my webservice return me : 

System.NotImplementedException: The requested feature is not implemented.

I'm using the NETProvider-3.1.0.0-MONO_LINUX version of the provider (http://www.firebirdsql.org/en/net-provider/). Apparently this method is not yet implemented in Mono, but as I don't have the source code, do you have any idea of some workaround ? I'm pretty sure there must be one because if not, this provider made for mono is totaly useless and not tested... :(

根据这篇文章，我通过使用驱动程序的先前版本（NETProvider-2.6.5-MONO_LINUX）找到了解决方案

有趣的是，有问题的驱动程序不再在 Firebird 官方网站上列出...无论如何，如果您有问题，请从 fb sourceforge 尝试这个：NETProvider-2.6.5-MONO_LINUX
