Open Visual Studio solution files - the classic text .sln and the newer XML .slnx (Visual Studio 2022 and the dotnet sln tooling) - in the browser: the solution format version and Visual Studio release, every project it groups (name, path, language and GUID) and the build configurations (Debug/Release platforms).

What is a .USERPREFS file?

USERPREFS is an XML file storing a developer’s per-solution IDE state - open documents, cursor positions and breakpoints - for MonoDevelop / Unity’s old script editor.

Did you know: Because it only holds personal editor state, .userprefs is one of the files projects usually exclude from version control.
Analyser handles .USERPREFS alongside related formats such as .SLN, .SLNX.
In Analyser's format library, .USERPREFS sits in the Data & code category.
