creating a web api using asp.net core 8 following the principles of clean architecture involves several steps. clean architecture emphasizes separation of concerns, making your application easier to maintain and test. below is a step-by-step tutorial that covers the essentials to get you started, including code examples.

prerequisites

.net sdk (8.0 or later)
visual studio or visual studio code
basic understanding of c and asp.net core

1. set up your project structure

first, create a solution to organize your project. open a terminal and run the following commands:

```bash
mkdir cleanarchitecturedemo
cd cleanarchitecturedemo
dotnet new sln
```

next, create the projects that will represent different layers of the clean architecture:

```bash
dotnet new classlib -n cleanarchitecturedemo.domain
dotnet new classlib -n cleanarchitecturedemo.application
dotnet new webapi -n cleanarchitecturedemo.api
dotnet new classlib -n cleanarchitecturedemo.infrastructure
```

add these projects to the solution:

```bash
dotnet sln add cleanarchitecturedemo.domain/cleanarchitecturedemo.domain.csproj
dotnet sln add cleanarchitecturedemo.application/cleanarchitecturedemo.application.csproj
dotnet sln add cleanarchitecturedemo.api/cleanarchitecturedemo.api.csproj
dotnet sln add cleanarchitecturedemo.infrastructure/cleanarchitecturedemo.infrastructure.csproj
```

2. define domain layer

the domain layer contains the core business logic. create a simple entity in the `domain` project.

create a product entity

```csharp
// cleanarchitecturedemo.domain/product.cs
namespace cleanarchitecturedemo.domain
{
public class product
{
public int id { get; set; }
public string name { get; set; }
public decimal price { get; set; }
}
}
```

3. create application layer

the application layer contains the business logic and interfaces. create a simple interface and a command for adding a product.

create interfaces and commands

```csharp
// cleanarchit ...
