I am trying to convert the famous BingSearchContainer.cs class file to .dll so that I can use it in a vb.net project. I have read and followed every single step mentioned in here
http://footyntech.wordpress.com/2011/07/27/creating-and-using-dll-files/
however when I compile it gives me several errors shown in the bottom screenshot

I also tried to change the .NET Framework from 3.5 to 4.0 and vise versa, but without luck.
Any thoughts or suggestions ?
You have to reference the required assemblies used by your code, e.g. System.Data.dll. With the command line Compiler you do that with the switch /r
For every data type that is missing you have to check in the MSDN in which assembly this data type is and add it to the list.
