What files I need to check-in after adding a web service reference?

I have a (new) project and it has a web service reference. It has following structure: ``` <Folder: project folder> <File: source file 1> <File: source file 2> <File: source file .> Folder: Web References Folder: MyService File: Reference.map File: Reference.cs File: MyService.xsd File: MyService0.xsd File: MyService.wsdl File: MyService0.wsdl File: MyService0.disco ``` I am about to check-in the source code to version control system. Which files I must check-in?
