WalkthroughThis update introduces a new C# project called "BadCodeProject" designed to demonstrate poor coding practices. It adds intentionally badly formatted and styled C# source files, a solution file, and project files. Additionally, two GitHub Actions workflows are created to automate linting and static code analysis using .NET and ReSharper on pull requests. Changes

Duplicate / orphaned project file will confuse the build & CI
The repo already containsBadCodeProject/BadCodeProject.csproj
, which is the one referenced by the solution and the GitHub-Actions workflows.
This top-levelBadCodeProject.csproj
is never referenced, points to a different (narrow) set of sources, and will be picked up bydotnet
CLI commands that glob for*.csproj
.
Expect at least one of these headaches:
•dotnet restore
/dotnet build
executed from repo root will try to restore & buildboth projects
• conflicting output paths / package assets
• CI time wasted on a project that should not exist
If the intent was to keep only the project underBadCodeProject/
, delete this file; otherwise move it to its own directory and reference it from a separate solution.
- BadCodeProject.csproj ⟵ delete (or move/rename)
