RSCG – PrimaryParameter    

Generating properties from .NET 8 constructor parameters

This is how you can use PrimaryParameter .

The code that you start with is

  <Project Sdk="Microsoft.NET.Sdk">    <PropertyGroup>     <OutputType>Exe</OutputType>     <TargetFramework>net8.0</TargetFramework>     <ImplicitUsings>enable</ImplicitUsings>     <Nullable>enable</Nullable>   </PropertyGroup>  	<PropertyGroup> 		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles> 		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath> 	</PropertyGroup>  	<ItemGroup> 	  <PackageReference Include="FaustVX.PrimaryParameter.SG" Version="1.2.0" OutputItemType="Analyzer" ReferenceOutputAssembly="false"  /> 	</ItemGroup> </Project>   

The code that you will use is

  using QuickConstructorDemo;  var p = new Person("Andrei","Ignat");  Console.WriteLine(p.FullName());  

  using PrimaryParameter.SG; namespace QuickConstructorDemo; internal partial class Person([Property]string FirstName,[Field(Name ="_LastName",Scope ="public")]string? LastName=null) {     //private readonly string FirstName;     //private readonly string? LastName;          public string FullName() => $"{FirstName} {_LastName}";      }   

  The code that is generated is

 namespace QuickConstructorDemo {     partial class Person     {         public string FirstName { get; init; } = FirstName;     } } namespace QuickConstructorDemo {     partial class Person     {         public readonly string _LastName = LastName;     } }  

 using global::System; namespace PrimaryParameter.SG {     [AttributeUsage(AttributeTargets.Parameter,Inherited = false,AllowMultiple = true)]     sealed class FieldAttribute : Attribute     {         public string Name { get; init; }         public string AssignFormat { get; init; }         public Type Type { get; init; }         public bool IsReadonly { get; init; }         public string Scope { get; init; }     } } 

 using global::System; namespace PrimaryParameter.SG {     [AttributeUsage(AttributeTargets.Parameter,Inherited = false,AllowMultiple = true)]     sealed class PropertyAttribute : Attribute     {         public string Name { get; init; }         public string AssignFormat { get; init; }         public Type Type { get; init; }         public bool WithInit { get; init; }         public string Scope { get; init; }     } } 

 using global::System; namespace PrimaryParameter.SG {     [AttributeUsage(AttributeTargets.Parameter,Inherited = false,AllowMultiple = true)]     sealed class RefFieldAttribute : Attribute     {         public string Name { get; init; }         public string Scope { get; init; }         public bool IsReadonlyRef { get; init; }         public bool IsRefReadonly { get; init; }     } }
