The type initializer for 'Sybase.Data.AseClient.AseConnection' threw an exception

I created ASP.Net web application in Visual Studio 2013. This application uses Sybase.Data.AseClient.dll to connect to Sybase database.

When I press F5 and debug application then it runs fine. No issues. But when I publish it using VS in C:\inetpub\wwwroot folder then I get following error when trying to browse the website:

The type initializer for 'Sybase.Data.AseClient.AseConnection' threw an exception.

How do I fix this issue?

EDIT

Inner exception being thrown is shown below.
