Open SLN File

An SLN file extension is a proprietary file structure, developed by Microsoft, and is used to organize projects in Visual Studio.

About Visual Studio

Visual Studio is a multilanguage IDE developed by Microsoft that is widely used to create software for desktop, mobile, web development, cloud computing, and much more.

The latest version is 2022 or 17.2.

The SLN contains text-based information about the environment and status of the project.

When opened, the preSolution, Project, and postSolution information is read from the SLN file.

This data, stored in the SLN, is used to load the solution, the projects within the solution, and any persistent data attached to the solution.

SLN files are similar to the VBG extension Windows Program Group files used by Visual Basic.
