This will generate code for investigating at runtime the properties of an object

This is how you can use ApparatusAOT .

The code that you start with is

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

	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net7.0</TargetFramework>
	</PropertyGroup>

	<ItemGroup>
		<PackageReference Include="Apparatus.AOT.Reflection" Version="0.2.0" />
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

</Project>

The code that you will use is

using Apparatus.AOT.Reflection;
using ApparatusDemo;
using System;

Person p1 = new();
p1.FirstName = "Andrei1";
p1.LastName = "Ignat1";

Person p2 = new ();

var prop =p1.GetProperties().Values;
foreach (var item in prop)

    Console.WriteLine($"{item.Name} Attr: {item.Attributes.Length} value {item.Name}");
    if (item.TryGetValue(p1, out var val))
    {

RSCG – RazorBlade
 
 

Fast templating with Razor syntax

Do not forget to put into AdditionalFiles section of csproj file

This is how you can use RazorBlade .

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>
	<ItemGroup>
		<PackageReference Include="RazorBlade" Version="0.4.3" PrivateAssets="all" ReferenceOutputAssembly="false" OutputItemType="Analyzer" />
	</ItemGroup>
	<ItemGroup>
		<AdditionalFiles Include="PersonDisplay.cshtml" />
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using RazorBladeDemo;

Console.WriteLine("Hello, World!");
Person p = new();
p.FirstName= "Andrei";
p.LastName = "Ignat";


var template = new PersonDisplay(p);
var result = template.Render();
Console.WriteLine(result);

namespace RazorBladeDemo;

public class Person
{
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public string FullName()
    {
        return FirstName + " "+LastName;
    }
}

@using RazorBladeDemo;
@inherits RazorBlade.HtmlTemplate<Person>;

This is the @Model.FirstName @Model.LastName

<br />

This should be full name of @Model.FullName()

RSCG – Vogen
 
 

Transform values( e.g. int) into classes

If you know what are ValueObject,that is one solution

This is how you can use Vogen .

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>

  <ItemGroup>
    <PackageReference Include="Vogen" Version="3.0.16" />
  </ItemGroup>
<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information

using DemoVogen;

Console.WriteLine("Hello, World!");
var p = PersonId.From(123);
var p1 = PersonId.From(123);
var p2 =(PersonId) 123;

Console.WriteLine(p == 123);
Console.WriteLine(p == p1);
Console.WriteLine(p == p2);

// See https://aka.ms/new-console-template for more information
using Vogen;
namespace DemoVogen;
[ValueObject<int>]
public partial struct PersonId
{
}

RSCG – dunet
 
 

Add union types to C# – similar with F#/TS discriminated unions

Check his examples- awesome

This is how you can use dunet .

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>

	<ItemGroup>
		<PackageReference Include="Dunet" Version="1.8.0">
			<PrivateAssets>all</PrivateAssets>
			<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
		</PackageReference>
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

</Project>

The code that you will use is

// See https://github.com/domn1995/dunet for more examples
using duneDemo;
Console.WriteLine(WhatIsTheString.FromString("1"));

Console.WriteLine(WhatIsTheString.FromString("Andrei"));

Console.WriteLine(WhatIsTheString.FromString("1970-04-16"));

Console.WriteLine("Enter something - 1, 1970-04-16 or Andrei !");
var readLine = Console.ReadLine();
var opt= WhatIsTheString.FromString(readLine);
Console.WriteLine(opt);
//if if it long
opt.MatchIsLong(
    l => Console.WriteLine("is long " + l.value),
    () => Console.WriteLine("is not long")
    ) ;
//C# switch
var x=opt switch
{
    WhatIsTheString.IsLong l => "is long " +l.value,
    WhatIsTheString.IsDate d=> "is date "+ d.value,
    WhatIsTheString.IsString s=>"is string "+ s.value,
    WhatIsTheString.IsNullWhiteSpace w=>"no data",
    _ => throw new NotImplementedException()

};
Console.WriteLine(x);

using Dunet;
namespace duneDemo;

[Union]
partial record WhatIsTheString
{
    partial record IsString(string value);
    partial record IsLong(long value);
    partial record IsDate(DateTime value);

    partial record IsNullWhiteSpace();

    public static WhatIsTheString FromString(string? value)
    {
        if (string.IsNullOrWhiteSpace(value))
            return new IsNullWhiteSpace();

        if(long.TryParse(value, out var longValue))
        {
            return new IsLong(longValue);
        }
        if(DateTime.TryParse(value, out var dateTimeValue))
        {
            return new IsDate(dateTimeValue);
        }
        return new IsString(value);
    }

}

RSCG – AutoCtor
 
 

Generate constructor from non-initialized fields

This is how you can use AutoCtor .

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="AutoCtor" Version="1.0.0" />
	</ItemGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using AutoCtorDemo;

Console.WriteLine("Hello, World!");

var p = new Person("Andrei", "Ignat");

using AutoCtor;

namespace AutoCtorDemo;

[AutoConstruct]
internal partial class Person
{
    private readonly string FirstName;
    private readonly string? LastName;

}
