Generate fluent builder

This is how you can use Fluentify .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
  </PropertyGroup>

	  <PropertyGroup>
        <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
    </PropertyGroup>

	  <ItemGroup>
	    <PackageReference Include="Fluentify" Version="1.1.0">
	      <PrivateAssets>all</PrivateAssets>
	      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
	    </PackageReference>
	  </ItemGroup>

	  
</Project>

The code that you will use is

using Builder;

var pOld = new Person();
pOld= pOld.WithFirstName("Andrei").WithLastName("Ignat").WithMiddleName("G");

System.Console.WriteLine(pOld.FullName());

namespace Builder;
[Fluentify.Fluentify]
public partial class Person
{
    public string FirstName { get; init; }
    public string? MiddleName { get; init; }
    public string LastName { get; init; }

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

The code that is generated is
