Franz.Common.Http.EntityFramework 1.6.19

Franz.Common.Http.EntityFramework

A specialized library within the Franz Framework that integrates Entity Framework Core with ASP.NET Core applications. This package simplifies transactional handling, dependency injection, and middleware configurations, enhancing database operations in HTTP-based services.

Features

• Transactional Filters:

  • TransactionFilter for managing database transactions seamlessly in API requests.

• Service Registration:

  • ServiceCollectionExtensions for registering database contexts and transactional filters.

• Entity Framework Core Integration:

  • Built-in support for relational database operations.

• Multi-Database Provider Support (since 1.3.4, extended in 1.6.2 & 1.6.3):

  • Configure MariaDB, Postgres, Oracle, or SQL Server via appsettings.json.
  • Since 1.6.2 → Polyglot persistence: support for MongoDB and Azure Cosmos DB as first-class NoSQL providers.
  • New in 1.6.3 → Environment-aware multi-database registration with provider validation, preventing silent misconfigurations.

• Modular Design:

  • Compatible with other Franz Framework persistence components, such as:

    • Franz.Common.EntityFramework.MariaDB
    • Franz.Common.EntityFramework.Postgres
    • Franz.Common.EntityFramework.Oracle
    • Franz.Common.EntityFramework.SQLServer
    • Franz.Common.MongoDB
    • Franz.Common.AzureCosmosDB

Version Information

• Current Version: 1.6.19 → Adds environment-aware validation, stronger governance for multi-database setups, and provider-context alignment.
• Part of the private Franz Framework ecosystem.

• Microsoft.EntityFrameworkCore (8.0.0)
• Microsoft.EntityFrameworkCore.Relational (8.0.0)
• Microsoft.AspNetCore.Mvc (2.2.0)
• Franz.Common.DependencyInjection
• Franz.Common.EntityFramework.MariaDB
• Franz.Common.EntityFramework.Postgres
• Franz.Common.EntityFramework.Oracle
• Franz.Common.EntityFramework.SQLServer
• Franz.Common.MongoDB (since 1.6.2)
• Franz.Common.AzureCosmosDB (since 1.6.2)

Installation

From Private Azure Feed

dotnet nuget add source "https://your-private-feed-url" \
  --name "AzurePrivateFeed" \
  --username "YourAzureUsername" \
  --password "YourAzurePassword" \
  --store-password-in-clear-text

Install the package:

dotnet add package Franz.Common.Http.EntityFramework

Usage

1. Configure Provider in appsettings.json

{
  "Database": {
    "Provider": "Postgres",
    "ConnectionString": "Host=localhost;Database=mydb;Username=myuser;Password=mypass"
  },
  "MongoDb": {
    "Provider": "Mongo",
    "ConnectionString": "mongodb://localhost:27017",
    "DatabaseName": "FranzMongoDb"
  },
  "CosmosDb": {
    "Provider": "Cosmos",
    "ConnectionString": "AccountEndpoint=https://your-account.documents.azure.com:443/;AccountKey=your-key;",
    "DatabaseName": "FranzCosmosDb"
  }
}

Supported providers: MariaDb, Postgres, Oracle, SqlServer, Mongo, Cosmos.

2. Register Database Context

builder.Services.AddDatabase<MyDbContext>(builder.Environment, builder.Configuration);

For multiple contexts (polyglot persistence):

builder.Services.RegisterDatabaseForContext<MyRelationalDbContext>(builder.Configuration.GetSection("Database"));
builder.Services.RegisterDatabaseForContext<MyMongoDbContext>(builder.Configuration.GetSection("MongoDb"));
builder.Services.RegisterDatabaseForContext<MyCosmosStore>(builder.Configuration.GetSection("CosmosDb"));

3. Enable Transaction Filters

Automatically applied by default, but can be explicitly added:

using Franz.Common.Http.EntityFramework.Transactions;

services.AddControllers(options =>
{
    options.Filters.Add<TransactionFilter>();
});

Integration with Franz Framework

The Franz.Common.Http.EntityFramework package integrates seamlessly with:

• Franz.Common.EntityFramework
• Franz.Common.EntityFramework.MariaDB
• Franz.Common.EntityFramework.Postgres
• Franz.Common.EntityFramework.Oracle
• Franz.Common.EntityFramework.SQLServer
• Franz.Common.MongoDB
• Franz.Common.AzureCosmosDB
• Franz.Common.DependencyInjection

Changelog

Version 1.6.3

• Environment-aware validation added to AddDatabase<TDbContext> and RegisterDatabaseForContext<TContext>:

  • Enforces correct provider/context alignment for relational (EF), MongoDB, and CosmosDB contexts.
  • Prevents silent misconfigurations (wrong provider/context combinations now throw explicit exceptions).
  • Guards against hardcoded connection strings — all values must come from appsettings.{Environment}.json.

• Governance baked in for relational DBs:

  • Automatic registration of transactions per HTTP call, generic repositories, and behaviors.

• Extended multi-database orchestration:

  • Support for mixing multiple contexts (MariaDB, Postgres, Oracle, SQLServer, MongoDB, CosmosDB) within the same app.
  • Polyglot persistence scenarios are now governed by clear, opinionated rules.

Version 1.6.2

• Extended multi-database provider support to include NoSQL providers:

  • Added MongoDB support via Franz.Common.MongoDB.
  • Added Azure Cosmos DB support via Franz.Common.AzureCosmosDB.

• AddDatabase<TDbContext> now supports both relational and document database providers via config.

• Introduced CosmosDBMessageStore and MongoMessageStore to unify outbox & dead-letter messaging in NoSQL providers.

• Full alignment with Franz polyglot persistence philosophy.

Version 1.3.4

• Added multi-database provider support (MariaDB, Postgres, Oracle, SQL Server).
• Provider selection now handled via appsettings.json (Database:Provider).
• Simplified registration: AddDatabase<TDbContext>(env, config).

Version 1.3

• Upgraded to .NET 9.0.8
• Added new features and improvements
• Separated business concepts from mediator concepts
• Now compatible with both the in-house mediator and MediatR

Version 1.2.65

• Upgraded version to .NET 9
