Utilize the provided template accessible at the following link to seamlessly initiate a Clean Architecture project: https://www.nuget.org/packages/Clean.Architecture.Solution.Template. This template offers a structured foundation for your project, ensuring adherence to Clean Architecture principles. Simply leverage this resource to streamline the process of setting up a well-organized and maintainable project structure.

Hello Nitin,

Please follow the steps to create clean code architecture using command prompt, 

• Create a Solution:

dotnet new sln -n YourSolutionName

• Create Projects for Each Layer:

1.  Domain Layer:
2. Application Layer:
3. Infrastructure Layer:
4. Presentation Layer (e.g., Web API or MVC):

You can open the command prompt and run the command below to create a separate layer for each. it will create a respective layer for you. Then start adding respective code according to your project requirement

dotnet new classlib -n YourSolutionName.Domain -o YourSolutionName.Domain

dotnet new classlib -n YourSolutionName.Application -o YourSolutionName.Application

dotnet new classlib -n YourSolutionName.Infrastructure -o YourSolutionName.Infrastructure

dotnet new webapi -n YourSolutionName.Api -o YourSolutionName.Api

Clean architecture is a software design principle that promotes separation of concerns and maintainability. It allows for the creation of modular, testable, and scalable applications. In .NET 8, you can follow these steps to create a project with clean architecture:

1. Start by defining the core domain of your application. This includes the business logic and entities that represent the problem domain.

2. Create separate projects for each layer of the clean architecture. These layers typically include the Presentation layer, Application layer, Domain layer, and Infrastructure layer.

3. In the Presentation layer, you can use ASP.NET Core MVC or Razor Pages to handle user interactions and display data. This layer should be responsible for handling HTTP requests and returning appropriate responses.

4. The Application layer acts as an intermediary between the Presentation and Domain layers. It contains the application-specific logic and orchestrates the flow of data between the layers.

5. The Domain layer represents the core business logic of your application. It should be independent of any specific technology or framework. Define your entities, value objects, and business rules in this layer.

6. The Infrastructure layer handles external dependencies such as databases, APIs, or third-party libraries. Use Entity Framework Core or any other ORM to interact with the database. Implement repositories and data access logic in this layer.

7. Use dependency injection to wire up the dependencies between the layers. This allows for loose coupling and easier testing.

8. Write unit tests for each layer to ensure the correctness of your code. Use mocking frameworks like Moq to isolate dependencies and make your tests more robust.

By following these steps, you can create a project with clean architecture in .NET 8. This approach promotes separation of concerns, maintainability, and testability, making it easier to develop and maintain your application over time.

Steps in Visual Studio:

1. Open Visual Studio
2. Launch Visual Studio and Create new Project
3. Right-click on the solution in Solution Explorer. and add the project refrences
4. Define the domain models, entities, and business logic in the Domain layer.
5. Implement use cases, services, and application logic in the Application layer.
6. Implement data access, repositories, and external services in the Infrastructure layer.
7. Create user interfaces or APIs in the Presentation layer.
8. Use the built-in DI container provided by ASP.NET Core (Microsoft.Extensions.DependencyInjection) or any preferred DI framework to manage dependencies between layers.
9. Write unit tests for each layer using testing frameworks like MSTest, xUnit, or NUnit to ensure the components work as expected.
10. Set up CI/CD pipelines using Azure DevOps, GitHub Actions, or any other preferred CI/CD tool for automated builds and deployments.
