Domain.SharedKernel is a clean, reusable shared library tailored for Domain-Driven Design (DDD) applications. It encapsulates core domain logic, base entity definitions, Snowflake ID generation, and abstraction contracts—ideal for use across multiple bounded contexts or microservices.

Install via NuGet:

dotnet add package Andrew.Domain.SharedKernel

NuGet\Install-Package Andrew.Domain.SharedKernel

"Snowflake": {
  "WorkerId": 1
}

ℹ️ Use different WorkerIds for each microservice instance or physical machine to avoid ID collisions.

services.AddDomainShardKernelCollection(configuration);

A common abstract base class for domain entities, offering:

• Unique identifier with Snowflake ID generation
• Domain event support (using [MediatR])

A utility class for secure hash generation:

• SHA256
• MD5
• AES

Useful for token generation, password hashing, and more.

Generates globally unique 64-bit IDs based on time and machine identity. Perfect for distributed systems that require high-performance and collision-free ID generation.

Includes key interfaces for domain architecture:

• IAggregateRoot – Marks an entity as an aggregate root.
• ICurrentUser – Access the current user context (UserId, TenantId, etc.).
• IUnitOfWork – Defines transactional boundaries for your repositories.

Implementing a Shared Kernel brings:

• 🔁 Consistency across bounded contexts
• 🧼 Separation of domain logic from infrastructure concerns
• 🔄 Reusability across projects and microservices
• 📐 Clarity through standard interfaces and patterns
