name: project-creator description: Create complete microservices project solutions using .NET 10 Minimal API backend with Dapr integration and Vite + React + Zustand frontend, orchestrated with .NET Aspire 13. Use this skill when the user wants to scaffold a new microservices solution, create a distributed application with API and frontend, set up a full-stack .NET + React project, or generate a modern cloud-native solution with orchestration. Triggers on requests involving microservices project, full-stack solution, .NET Aspire setup, API + frontend scaffold, distributed app creation.

Microservices Creator

Create modern microservices solutions with .NET 10 + React + Aspire orchestration following Kruchten's 4+1 architectural model.

Solution Architecture

The generated solution includes:

• Backend: .NET 10 Minimal API with OpenAPI + Scalar UI, Dapr integration
• Frontend: Vite + React + Zustand + Tailwind CSS + React Router
• Orchestration: .NET Aspire 13 AppHost for dev-time orchestration

Workflow

1. Gather user requirements (or use defaults)
2. Check prerequisites
3. Run automation script or follow manual workflow
4. Verify the solution works

Architecture Overview

This skill uses a single-source-of-truth template system to eliminate code duplication:

• Templates: Stored in assets/templates/ with {{PLACEHOLDER}} syntax
• Scripts: Thin orchestrators in scripts/ that read templates and substitute placeholders
• Documentation: references/REFERENCE.md references templates directly

Benefits:

• Update once in assets/templates/ → changes propagate everywhere
• Scripts are ~80 lines vs ~1100+ in previous version
• Manual workflow and automation use identical templates
• Easy to maintain and extend

Step 1: Gather Requirements

Ask only what is strictly necessary. Propose defaults and proceed if user accepts or doesn't respond:

Parameter	Default	Description
Solution name	MySolution	Name for solution and project folders
Root folder	Current directory	Where to create the solution
API HTTP port	5080	Backend HTTP port
API HTTPS port	7080	Backend HTTPS port
Web port	5173	Frontend dev server port

If user does not specify or says "use defaults", proceed automatically with defaults.

Step 2: Check Prerequisites

Before proceeding, verify:

• .NET 10 SDK installed (dotnet --version should show 10.x)
• Node.js 20+ installed (node --version)
• Aspire CLI installed (aspire --version should show 13.x)
• Docker or Podman running (for Aspire containers)
• Dapr CLI installed (dapr --version)
• Dapr initialized (dapr init must have been run)

Install Aspire CLI

Linux/macOS:

curl -fsSL https://aspire.dev/install.sh | bash

Windows PowerShell:

irm https://aspire.dev/install.ps1 | iex

Install Dapr CLI

Linux/macOS:

wget -q https://raw.githubusercontent.com/dapr/cli/master/install/install.sh -O - | /bin/bash
dapr init

Windows PowerShell:

powershell -Command "iwr -useb https://raw.githubusercontent.com/dapr/cli/master/install/install.ps1 | iex"
dapr init

Step 3: Generate Solution

Preferred approach: Run the automation script from scripts/ folder.

If scripts cannot run: Follow manual workflow in REFERENCE.md.

Using Scripts

Linux/macOS:

./scripts/create-solution.sh -n <SolutionName> -p <RootPath> --api-http 5080 --api-https 7080 --web 5173

Windows PowerShell:

.\scripts\create-solution.ps1 -Name <SolutionName> -Path <RootPath> -ApiHttp 5080 -ApiHttps 7080 -Web 5173

Manual Workflow

If scripts cannot be used, follow REFERENCE.md for step-by-step commands.

All templates are located in assets/templates/ organized by project type:

• servicedefaults/ - Shared service configuration
• microservice/ - Backend API with 4+1 architecture (used for initial API and added microservices)
• apphost/ - Aspire orchestration
• web/ - React frontend with Vite + Zustand

Step 4: Verify Solution (Definition of Done)

Run this checklist after generation:

• dotnet build completes successfully in solution root
• aspire run starts the AppHost
• Backend API runs and Scalar UI loads at https://localhost:7080/scalar/v1
• Frontend runs at http://localhost:5173 and can call the API (or has API endpoint wired via environment variables)

Quick Run Commands

After generation:

cd <SolutionName>
aspire run

This starts all services via the Aspire dashboard.

Adding New Microservices

To add a new microservice to an existing solution:

Using Scripts

Linux/macOS:

./scripts/add-microservice.sh -n <ServiceName> -s <SolutionPath>

Windows PowerShell:

.\scripts\add-microservice.ps1 -Name <ServiceName> -Solution <SolutionPath>

Options:

Parameter	Description
-n, --name	Service name (required, e.g., 'Orders', 'Products')
-s, --solution	Path to solution root (default: current directory)
--http	HTTP port (default: auto-assigned)
--https	HTTPS port (default: auto-assigned)

What the Script Does

1. Creates a new .NET 10 Minimal API project
2. Adds it to the solution
3. Registers it in the AppHost for Aspire orchestration
4. Configures health checks and OpenAPI with Scalar UI

After Adding a Service

1. Update AppHost.cs to add .WithReference() if the new service needs to call other services
2. Implement your domain logic and endpoints in the new service's Program.cs
3. Run aspire run to test

Manual Workflow

See REFERENCE.md for manual steps.

Architecture (Kruchten 4+1 View Model)

The solution follows Kruchten's 4+1 architectural views:

• Logical View: Domain models and business logic in API layer
• Process View: Async communication via Dapr pub/sub
• Development View: Modular project structure with clear separation
• Physical View: Container-ready services orchestrated by Aspire
• Scenarios: API endpoints as use case implementations

Template System

The skill uses a single-source-of-truth template system to eliminate duplication:

Template Organization

All templates are located in assets/templates/:

assets/templates/
├── servicedefaults/
│   ├── ServiceDefaults.csproj
│   └── Extensions.cs
├── microservice/                    # Used for both initial API and added services
│   ├── Microservice.csproj
│   ├── Program.cs
│   ├── appsettings.json
│   ├── appsettings.Development.json
│   ├── launchSettings.json
│   ├── Models/Model.cs
│   ├── Services/IService.cs
│   ├── Services/Service.cs
│   ├── Endpoints/Endpoints.cs
│   └── Infrastructure/DaprStateStore.cs
├── apphost/
│   ├── AppHost.csproj
│   ├── AppHost.cs
│   ├── appsettings.json
│   ├── appsettings.Development.json
│   └── launchSettings.json
├── web/
│   ├── package.json
│   ├── vite.config.ts
│   ├── src/App.tsx
│   ├── src/main.tsx
│   ├── src/components/...
│   ├── src/pages/...
│   └── ...
└── README.md

Placeholder Convention

Templates use {{PLACEHOLDER}} syntax for variable substitution:

Placeholder	Description	Example Value
{{SOLUTION_NAME}}	C# namespaces and project names	MyCompany.Orders
{{SOLUTION_NAME_LOWER}}	Lowercase for package names	mycompany-orders
{{PROJECT_NAME}}	Full project name (for microservices)	MyCompany.Orders
{{SERVICE_NAME}}	Service name (for microservices)	Orders
{{SERVICE_NAME_LOWER}}	Lowercase service name	orders
{{API_HTTP_PORT}}	HTTP port for API	5080
{{API_HTTPS_PORT}}	HTTPS port for API	7080
{{HTTP_PORT}}	HTTP port (microservices)	5100
{{HTTPS_PORT}}	HTTPS port (microservices)	6100
{{WEB_PORT}}	Frontend dev server port	5173

How It Works

1. Scripts read templates from assets/templates/
2. Substitute placeholders with user-provided or default values
3. Write to destination in the generated solution

Shell script example:

sed -e "s|{{SOLUTION_NAME}}|$SOLUTION_NAME|g" \
    -e "s|{{API_HTTPS_PORT}}|$API_HTTPS_PORT|g" \
    template.txt > output.txt

PowerShell example:

(Get-Content template.txt) -replace '{{SOLUTION_NAME}}','MyApp' | 
    Set-Content output.txt

Benefits

• ✅ Single source of truth: Update template once, changes propagate everywhere
• ✅ Maintainability: Scripts reduced from 1100+ lines to ~250 lines
• ✅ Consistency: Manual workflow and automation use identical templates
• ✅ Extensibility: Easy to add new project types or modify existing ones
• ✅ Testability: Templates can be validated independently of scripts

Updating Templates

To modify the generated solution structure:

1. Edit files in assets/templates/
2. Test with ./scripts/create-solution.sh -n TestSolution
3. Verify both automated and manual workflows work
4. Document changes in REFERENCE.md if needed

No need to update:

• Scripts (they read from templates automatically)
• Documentation (references templates directly)
