vs.net 2010 tfs checking in

a few questions about vs.net 2010 tfs in a multi developer 开发者_JAVA技巧environment: 1. should it be checking in code first and then 'get latest' or vice versa in order not to break the build? 2. is it possible to checkin just one file without breaking the build?

You should get the latest version before checking in and merging changes from TFS with your edits. If you would just check in your changes the files on TFS would get replaced with your versions, removing any changes commited by others.
