-## The Book - Microservices Architecture and Step by Step Implementation on .NET
-
-You can find **Microservices Architecture and Step by Step Implementation on .NET book** which **step by step developing** this repository with extensive explanations and details. This book is the **best path to leverage your .NET skills** in every aspect from beginner to senior level you can benefit to ramp-up faster on **Enterprise Application Development practices** and easy to **Onboarding to Full Stack .Net Core Developer jobs**. 
-
-The book also includes more practical information and I **update it regularly** and send it again with new versions.
-So the idea is once you buy a book, I take this as **supporting me** and **join them in my privilege group** for sharing **next outputs**.
-For example I am planning to add **IdentityServer4 implementation**, firstly I added it into a book and sent it to you.

-# What is AspnetRun ? 
-The best path to **leverage your ASP.NET Core** skills. Onboarding to **Full Stack .Net Core Developer** jobs. Boilerplate for **ASP.NET Core reference application** with **Entity Framework Core**, demonstrating a layered application architecture with DDD best practices. Implements NLayer **Hexagonal architecture** (Core, Application, Infrastructure and Presentation Layers) and **Domain Driven Design** (Entities, Repositories, Domain/Application Services, DTO's...) 
-and aimed to be a **Clean Architecture**, with applying **SOLID principles** in order to use for a project template. 
-Also implements **best practices** like **loosely-coupled, dependency-inverted** architecture and using **design patterns** such as **Dependency Injection**, logging, validation, exception handling, localization and so on.
