.SUO is Visual Studio Solution User Options File

User information file that stores data in a structured binary format; referenced by VSPackages created with Visual Studio; opened by the LoadUserOptions Method and modified by the WriteUserOptions and SaveUserOptions methods.

If you are a developer, you do not need to store SUO files under version control (e.g., Git or Subversion) since these files are specific to your machine and Visual Studio installation. Additionally, since SUO files change each time you use an associated Visual Studio solution (.SLN) and they are saved in a binary format, they become difficult to place under version control.
