Hi,
SolutionName.crunchsolution.local.xml is clearly a user specific file, the convention for User Specific Configuration Information additional to Visual Studio Solution and Visual Studio Project is that the file is ended with .user and not .local.xml
With that convention it is easy to exclude user specific configuration in the version control system (*.user). With "your" convention, it is not ;)
Best Regards
PS: If you have project specific user files, please follow the same convention.
