Registration

Goal

This snapshot advances Rivergate Market by teaching you to validate customer accounts and store password hashes.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use .NET 8 SDK and Docker for Postgres stages.

Port 5082 must be free. Copy .env.example before database stages.

• .NET 8 SDK
• A code editor and terminal
• Docker from part 4 onward

Concepts

Registration normalizes email, enforces uniqueness, hashes passwords, signs the user in, and regenerates the session.

Razor Pages keep handlers close to markup; cookie auth owns the session; EF Core persists catalog and orders.

Walkthrough

Build a registration form with CSRF-safe posts and validation errors.

Read the example, then open the matching snapshot. The repository includes validation, CSRF, and the surrounding structure.

user.PasswordHash = hasher.HashPassword(user, input.Password);
db.Users.Add(user); await db.SaveChangesAsync();
await HttpContext.SignInAsync(...);

Run and verify

Enter 06-Registration, copy .env.example, restore, migrate, and dotnet run on port 5082.

Open http://127.0.0.1:5082. From data lessons onward, Ada and Grace use password123.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-aspnet-ecommerce.git
cd fcc-aspnet-ecommerce/06-Registration
cp .env.example .env
dotnet restore
dotnet ef database update
dotnet run --urls http://0.0.0.0:5082

Troubleshooting

Duplicate email and password confirmation failures should redisplay field errors.

For database failures, confirm Docker and the river_NN name. Never commit .env, bin/, obj/, or secrets.

• Read the first exception first
• Rebuild assets after Tailwind class changes
• Never commit secrets

Try this

Try a short password, mismatched confirmation, and a duplicate email.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
