dotnet-project-structure

Reference guide for modern .NET project structure and solution layout. Use when creating new solutions, reviewing existing structure, or recommending improvements.

Prerequisites: Run [skill:dotnet-version-detection] first to determine TFM and SDK version — this affects which features are available (e.g., .slnx requires .NET 9+ SDK).

Scope

• Solution layout conventions (.sln, src/, tests/)
• Directory.Build.props and Directory.Build.targets shared config
• Central Package Management (CPM) and lock files
• .editorconfig and analyzer configuration
• SourceLink, NuGet Audit, and nuget.config

Out of scope

• Build output organization (UseArtifactsOutput) -- see [skill:dotnet-artifacts-output]
• MSBuild authoring (custom targets, conditions) -- see [skill:dotnet-msbuild-authoring]
