EntityInjector

EntityInjector is a set of libraries designed to simplify extracting entities from (primarily) databases in a clean and dependency-injected way.

👉 This repository contains multiple NuGet packages:

• EntityInjector.Route — Route binding to entities (via HTTP context)
• EntityInjector.Property — (coming soon)

Packages

Package	NuGet	Description
EntityInjector.Route		Bind route parameters directly to database entities

Samples

We provide samples using Postgres + EF Core + TestContainers. See: EntityInjector.Samples.PostgresTest

Development

• Requires .NET 8 SDK
• Tests use docker containers

Roadmap

• Add Cosmos DB sample
• Extend tests + failure scenarios
• Exception handling

EntityInjector.Samples.PostgresTest

This sample demonstrates how to use EntityInjector with a Postgres database using Entity Framework Core and TestContainers.
It shows how to bind route parameters directly to entities using dependency injection.

Prerequisites

• Docker installed and running
• .NET 8 SDK installed

How to run

1. From the repository root, start the database using Docker Compose:

docker compose up --build

This will create a Postgres container and run init.sql to seed the database with test data.

2. From the sample project directory, build and run the tests:

dotnet clean && dotnet restore && dotnet test
