RSCG – Fluentify
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
