C# Solution Explorer
A lightweight Solution Explorer for C# projects in VS Code — and in Open VSX-compatible editors such as VSCodium.
Vision
The long-term goal is a VS Code extension that gives C# (and Razor) developers everything they need to write and debug their code, without depending on Microsoft-proprietary-only extensions (like C# Dev Kit) that aren't available on Open VSX. That full scope — language features, IntelliSense, debugging — is not part of this version.
Features
Dedicated Activity Bar view showing Solution → Solution Folders → Projects → Folders/Files.
Parses .sln and .slnx solution files, including Solution Folder nesting.
Falls back to a loose top-level .csproj when no solution file is found.
Folders and files are read directly from disk (no MSBuild evaluation), excluding bin, obj, node_modules, and hidden directories.
Manual refresh button and automatic refresh via a file system watcher.
Click a file to open it in the editor.
