Question

What is the difference the between sln file and suo in c#

Manas Mohapatra · Answer

SLN stands for Solutions It stores info about the collection of projects that make up whatever you are developing. They contain projects source control settings or any other global level thing. Suppose you have class library one console application Web application and .sln file reference to all projects. So when you click on solution file it loads all projects. CSProj (Project file) are the actual code projects (C# Libraries WCF Services etc). It stores information at the project level. It wraps all relevant References Classes etc.. SUO (solution user options) are user settings files. Completely disposable you can remove it and the most common thing you can't see where were the breakpoints.
