I think this is the error he is refering to because I have it too:

Error 1 The type or namespace name 'NetworkAdapter' could not be found (are you missing a using directive or an assembly reference?) c:\users\electron\documents\visual studio 2013\Projects\Network Card\Network Card\Form1.cs 50

Then you need to add the library to your references and include a using statement for the namespace.
