   • src/PowderCoating.Web/appsettings.json
   • src/PowderCoating.Api/appsettings.json

   For LocalDB (default):

   "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=PowderCoatingDb;Trusted_Connection=true;MultipleActiveResultSets=true"
   

   For SQL Server Express:

   "DefaultConnection": "Server=.\\SQLEXPRESS;Database=PowderCoatingDb;Trusted_Connection=true;MultipleActiveResultSets=true"
   

   For Full SQL Server:

   "DefaultConnection": "Server=YOUR_SERVER_NAME;Database=PowderCoatingDb;Trusted_Connection=true;MultipleActiveResultSets=true"
   

2. Create Database - Run migrations:

   cd src/PowderCoating.Web
   dotnet ef database update --project ../PowderCoating.Infrastructure
   

Step 4: Run the Application

Option A: Visual Studio

Development Workflow

Adding Your First Feature

1. Create Entity in PowderCoating.Core/Entities/
2. Add to DbContext in Infrastructure/Data/ApplicationDbContext.cs
3. Create Migration:

   dotnet ef migrations add YourFeatureName --project src/PowderCoating.Infrastructure --startup-project src/PowderCoating.Web
   

4. Update Database:

   dotnet ef database update --project src/PowderCoating.Infrastructure --startup-project src/PowderCoating.Web
   

5. Create DTOs in Application/DTOs/
6. Create Controller in Web/Controllers/
7. Create Views in Web/Views/[ControllerName]/

See DEVELOPMENT.md for detailed examples!

AI Features Setup (Optional)

OpenAI Integration for Intelligent Quoting

1. Get API key from https://platform.openai.com
2. Update appsettings.json:

   "AI": {
     "OpenAI": {
       "ApiKey": "sk-your-key-here",
       "Model": "gpt-4",
       "Endpoint": "https://api.openai.com/v1"
     }
   }
   

3. Implement IQuoteAIService in Application layer
4. Use in quote generation workflow

ML.NET for Price Prediction

1. Collect historical job data
2. Train model using ML.NET
3. Integrate predictions in quoting process
4. See ML.NET documentation for model training

Troubleshooting

"Cannot connect to database"

• Verify SQL Server is running
• Check connection string is correct
• Try connecting with SSMS first
• Check Windows Firewall settings

"The entity type 'X' requires a primary key to be defined"

• Run migrations: dotnet ef database update
• If persists, delete database and recreate

"Port already in use"

• Change ports in Properties/launchSettings.json
• Or kill the process using the port

NuGet Restore Issues

dotnet restore --force
dotnet clean
dotnet build
