## 1. Crear Solución y Proyectos

```bash
cd src/backend

# Crear solución
dotnet new sln -n StudentEnrollment

# Crear proyectos
dotnet new classlib -n Domain -f net10.0
dotnet new classlib -n Application -f net10.0
dotnet new classlib -n Adapters.Driving.Api -f net10.0
dotnet new classlib -n Adapters.Driven.Persistence -f net10.0
dotnet new web -n Host -f net10.0

# Agregar a solución
dotnet sln add Domain/Domain.csproj
dotnet sln add Application/Application.csproj
dotnet sln add Adapters.Driving.Api/Adapters.Driving.Api.csproj
dotnet sln add Adapters.Driven.Persistence/Adapters.Driven.Persistence.csproj
dotnet sln add Host/Host.csproj
```

## 2. Referencias entre Proyectos

```bash
# Application → Domain
dotnet add Application reference Domain

# Adapters.Driving.Api → Application
dotnet add Adapters.Driving.Api reference Application

# Adapters.Driven.Persistence → Domain
dotnet add Adapters.Driven.Persistence reference Domain

# Host → Todos
dotnet add Host reference Application
dotnet add Host reference Adapters.Driving.Api
dotnet add Host reference Adapters.Driven.Persistence
```

```
Host
├── Adapters.Driving.Api → Application → Domain
└── Adapters.Driven.Persistence ────────→ Domain
```
