Easily switch to different Visual Studio settings when...

• docking your laptop, or when it's undocked and you're on the go.
• presenting a live screencast.
• recording a how-to video.
• working on open source software with different code formatting requirements.
• an update to Visual Studio or a bad VS extension resets your desired settings.

• Solution Settings Files: Whenever a solution is opened, if a settings file of the same name (Solution_Name.vssettings) exists next to the solution file (Solution_Name.sln), its settings are automatically applied.
• Associates the current settings with the active solution. The associated settings will be applied automatically whenever the solution is opened. (Overrides the active Solution Settings File without modifying it.)
• Provides a toolbar (shown above).
  • Selecting an item in the drop-down list immediately imports those settings into Visual Studio.
  •  Export Current Settings saves the current settings to a file.
  •  Export Solution Settings saves the current settings to the active solution's settings file, or creates a new Solution Settings File and adds it to the solution.
  •  Format Solution formats all documents in the solution according to the current settings.
