🚀 AI can generate CRUD code in seconds. But configuring database permissions correctly—and verifying that they work—is a different engineering challenge.
In this hands-on tutorial, you’ll learn how to configure SQL Server access for a C# .NET 10 business application using the Principle of Least Privilege.
We’ll go step by step through SQL Server Management Studio (SSMS 22) and Visual Studio 2026, from database setup and login configuration to security validation and application-level CRUD testing.
What you’ll learn:
• Apply the Principle of Least Privilege to a SQL Server application login.
• Create a dedicated SQL Server Login and map it to a database user.
• Configure database roles (db_datareader & db_datawriter) for intended operations.
• Run database setup and sample data generation scripts.
• Test database permissions in SSMS, verifying restricted operations like DROP TABLE and CREATE DATABASE are blocked.
• Configure the connection string securely in appsettings.json.
• Run a C# .NET 10 business application and test CRUD operations via the UI.
• Understand how the application implements Soft Delete functionality.
• Use a Deployment Security Checklist to verify your configuration before delivery.
• Prompt AI tools effectively to explain SQL scripts and deepen your engineering judgment.
⚠️ Important: This walkthrough uses a test database. The setup script may drop and recreate the database, so never run it against a production environment. Always replace demonstration credentials and apply appropriate secrets-management strategies before deploying a real application.
