Welcome to the ASP.Net Core Repository Pattern starter project for developers. This project aims to provide a comprehensive starting point for implementing repository patterns with Unit of Work in your projects, enhancing code maintainability, and promoting best practices in software development.
If you find this project useful helpful in implementing Repository pattern in your ASP.NET Core project, please give it a star, on GitHub to help others developers discover it! Thanks

Repository pattern is a popular design pattern used in software development, including C# and .NET applications, especially in the context of domain-driven design and object-relational mapping (ORM). The repository pattern acts as a bridge between the business logic layer and the data access layer of an application by providing an abstraction layer over the data access layer. It allows the business logic to interact with the database without needing to know the underlying data access complexities.
Before you begin, ensure you have the following installed:
- .NET SDK (Version .Net 6 or later)
- An IDE of your choice (e.g., Visual Studio, VS Code)
- Basic Understanding of ASP.NET Core Web API concepts. To have a deeper understanding of the Repository Pattern you can read my article Repository and Unit of Work Patterns in ASP.NET Core: A Key to Cleaner C# Code and Architecture
- Clone the repository:
git clone https://github.com/ulomaramma/repository-pattern
- Navigate to the project directory:
cd repository-pattern - Install dependencies:
dotnet restore
The Repository Pattern and Unit of Work are key design patterns used in application development to separate the data access logic and business logic from the rest of the application. This guide implements these patterns using a Generic Repository, which provides a flexible and reusable way to access data across the application.
Figure 1: Overview of the Repository Pattern
The above diagram illustrates the basic structure and components involved in the Repository Pattern. The use of a Generic Repository ensures that common data operations (such as CRUD operations) are abstracted, thereby promoting code reusability and maintainability.
This guide's project is structured into three main projects to separate concerns and ensure a clean architecture:
- DataAccess.Core: Contains the repository and unit of work, alongside db context and migration classes.
- Domain: This project houses the domain entities (models) used throughout the application.
- WebAPI: The entry point of the application, this project references both the DataAccess.Core and Domain projects to serve data through a RESTful API.
Figure 2: Project Structure in Visual Studio
As depicted in Figure 2, the solution is organized to clearly separate the different aspects of the application, making it easier for developers to navigate and maintain the codebase.
The Generic Repository implemented in this guide abstracts away the specifics of the data access layer. By using interfaces defined in the DataAccess.Core project, it allows for more flexible data operations that can work with any entity type. This approach not only simplifies the codebase but also enhances its extensibility for future development.
To integrate the Repository Pattern and Unit of Work with your data management, you'll need to configure your database connection. This can be configured in your ppsettings.json file with the following connection string:
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=YourDatabaseName;Trusted_Connection=True;MultipleActiveResultSets=true"
