Hello:
To work with Sharepoint development you need to add references as when required. I am hereby detailing all standard Sharepoint references you might require to deveope your application.
Just go to add reference section of your Visual Studio ( in my case 2005 ) and say Add Reference and then Browse through all the .net references you need to add.
Lemme know if you require further help on each references in detail.
Cheers;
