Issue
When adding a new MicrosoftGame.config file to a Visual Studio project by using the item template, any file names entered that don’t have a ".config" extension will have their file extensions replaced with ".config". For example, if a file named MicrosoftGame_profile.txt is added by using the item template, the resulting file name is MicrosoftGame_profile.config.
Workaround
You can change the file name by using Visual Studio Solution Explorer.
