Opening SLN files

Did your computer fail to open a SLN file? We explain what SLN files are and recommend software that we know can open or convert your SLN files.

What is a SLN file?

Files that contain the .sln file extension are most commonly associated with the Microsoft Visual Studio software application. These SLN files contain information about the project environment and the state of the project when the SLN file was created.

The SLN files that are created by the Microsoft Visual Studio software are stored in a text-based file format. When the Microsoft Visual Studio program opens a project file, the pre-solution and post-solution data for that file is read from the SLN file.

These files are similar in nature to the VBG files that are used by the Microsoft Visual Basic software program.
