Backend Modules

Backend modules for building secure, tenant-aware SaaS applications.

Overview

Primus Backend Modules provide reusable server-side functionality for .NET applications. The safest way to adopt them is through a validated release snapshot, not by assuming every documented module is equally mature.

Key Features

• Release-Snapshot Driven: Existing client-safe baselines stay frozen while current evolves
• Secure by Default: Built with security best practices
• Highly Configurable: Flexible provider system
• Honest Adoption Surface: Public baseline docs list only the modules we can stand behind for adoption
• Type Safe: Full .NET type safety

Start Here

• Core SaaS Release Baseline - exact package versions and known gaps for the current adoption line
• Modules Overview - adopter-facing module list only

Getting Started

1. Start with the release baseline page
2. Choose only the modules you need
3. Install the exact package versions from the selected docs line
4. Configure in Program.cs
5. Upgrade only when you intentionally move to a newer baseline

Each module follows a consistent pattern:

• Overview: What it does and why use it
• Installation: NuGet package installation
• Providers: Provider-specific guides
• Advanced: Customization and optimization
