Application was initially developed in VS 2008. It uses MySQL.data. Dll for connecting to MySQL database.
Application runs perfectly fine in Windows. But production environment is Debian with mono. Now copied entire solution in the Debian box.
Entire solution opens in monodevelop correctly. It doesn't throw any error in building. But while running - it throws following error – The file sending is in process.......... Error: System.

If the answer I gave was helpful, you should upvote/accept it! :) – bobbymcr Sep 17 '09 at 21:05.
Semaphore (as used here) is a Windows-only feature. I'm guessing you'll need a version of the client that is specifically compatible with Mono. You may want to look at the MySQL section of the Mono site and go from there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
