NPv.Common.Infrastructure.Db.Ef 1.6.0

Simple Generic Repository Library

📦 Version 1.6.0 — Entity Enhancements & LongText Support

Brief Description

A foundational infrastructure library designed to streamline Entity Framework Core data access by providing a generic repository pattern and a pluggable unit of work abstraction. It promotes consistency, reusability, and isolation of transactional logic across services, APIs, and background workers.

🚀 Getting Started Started

To integrate this library into your project:

• Add a reference to the package.
• Register your DbContext and IDbContextProvider in the service container.
• Use the provided interfaces and base types to simplify CRUD and transaction management.

✅ Quick Example

Create a custom ApplicationContext:

The following demonstrates how to create ApplicationContext:

public class ApplicationContext(DbContextOptions<ApplicationContext> options) : DbContext(options)
{
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);      
    
        foreach (var entityType in builder.Model.GetEntityTypes()
                     .Where(t => t.ClrType.IsSubclassOf(typeof(Entity))))
        {
            var entity = builder.Entity(entityType.ClrType);
            entity.Property("Id")
                  .ValueGeneratedOnAdd()
                  .HasValueGenerator<GuidV7ValueGenerator>();
        }

        UserMapping.ApplyMapping(builder);
        //other mappings

        DefaultString256MaxLengthMapping.ApplyMapping(builder);
    }
}

🛠 Usage

When adding a new entity to the database, the Id will be automatically generated via GuidV7ValueGenerator. Default string column length is limited to 256 characters unless marked with [LongText] or [MaxLength].

📜 Changelog
