.NET Project Initialization Skill

This skill discovers everything about a .NET solution needed for DotnetPilot to operate effectively.

Discovery Protocol

1. Solution File

• Search for *.slnx (modern) or *.sln (legacy) in current directory
• If multiple solutions: ask user which one to use
• Parse project references from solution file

2. Per-Project Analysis

For each project in the solution:

dotnet list <project.csproj> reference    # project references
dotnet list <project.csproj> package      # NuGet packages

Parse .csproj for:

• <TargetFramework> → net8.0, net9.0, net10.0, etc.
• <OutputType> → Exe, Library
• <Sdk> → Microsoft.NET.Sdk.Web (web), Microsoft.NET.Sdk (classlib)
• <IsPackable> → library intended for NuGet distribution
• <RootNamespace> → namespace convention

3. Framework Detection

Indicator	Detection
Test runner	xunit → xunit package; NUnit → NUnit package; MSTest → MSTest.TestAdapter
Mocking	Moq, NSubstitute, FakeItEasy in test project packages
Assertions	FluentAssertions, Shouldly in test project packages
ORM	Microsoft.EntityFrameworkCore → EF Core; Dapper → Dapper
Validation	FluentValidation or DataAnnotations (check for [Required] attributes)
CQRS	MediatR package presence
Mapping	AutoMapper or Mapster package presence
API style	[ApiController] attribute → controllers; MapGet/MapPost → minimal API

4. Architecture Style Detection

Analyze project reference graph:

Clean Architecture:

• Domain has 0 project references
• Application references only Domain
• Infrastructure references Domain + Application
• Api references Application + Infrastructure

Vertical Slices:

• Feature folders within a single project
• No strict layer separation

Flat:

• Single project or 2 projects (app + tests)

5. EF Core Context Discovery

Search for classes inheriting DbContext:

class *DbContext : DbContext
class *Context : DbContext

For each context, identify:

• Project location
• Database provider (from Use* call or package: Npgsql, SqlServer, Sqlite)
• Migrations assembly location
