Should I add the Visual Studio .suo and .user files to source control ?

Published on Monday, August 23, 2010

.suo and .user file are two types of hidden user files in Visual Studio project.

.suo file which is a binary file. .user file is the project user file which is a text file.

You don't need to add these 2 files to your source control (SCM) since they contain per-user settings and SUO (Solution User Options) records all of the options that you might associate with your solution so that each time you open it, it includes customizations that you have made.
