Hi Surajit,
Checkout the solution from To-Increase. They made a source control connector for TFS 2013. The concept of their solution is that a NAV database is equal to a TFS workspace and that seems to be exactly what you are looking for. With the to-increase solution you can develop your nav code like you do it today and take advantage of the full power of tfs. Even advanced scenarios like shelving, multiple checkouts on the same object etc. are supported.
In our company we are using this solution since 2010. We are using version control, automated testing and build automation with visual studio online in distributed teams.
Kind Regards,
Ron
