Adding decorators to an implementation of interface

This is how you can use Matryoshki .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
	<ItemGroup>
		<PackageReference Include="Matryoshki" Version="1.1.4" />
		<PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="7.0.0" />

	</ItemGroup>


</Project>

The code that you will use is

using Matryoshki.Abstractions;
Decorate<IPerson> // you can use Decorate<> alias if you prefer
    .With<AddLog>()
    .Name<PersonMatryoshka>();

var services = new ServiceCollection();

services.AddTransient<IPerson,Person>();
services.AddTransient<PersonMatryoshka,PersonMatryoshka>();
var serviceProvider = services.BuildServiceProvider();
var sp=serviceProvider.GetRequiredService<PersonMatryoshka>();
sp.FirstName = "Andrei";
sp.LastName = "Ignat";
Console.WriteLine(sp.FullName());

namespace MatryoshkiDemo;

internal class AddLog : IAdornment
{
    public TResult MethodTemplate<TResult>(Call<TResult> call)
    {        
        Console.WriteLine($"start Calling {call.MemberName}  !");
        var data    =call.Forward();
        Console.WriteLine($"end calling {call.MemberName} !");
        return data;

    }
}

namespace MatryoshkiDemo;

public interface IPerson
{
    string? FirstName { get; set; }
    int ID { get; set; }
    string? LastName { get; set; }

    string FullName();
}

namespace MatryoshkiDemo;

public class Person : IPerson
{
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }

    public string FullName()
    {
        return $"{FirstName} {LastName}";
    }
}

The code that is generated is
