Serializing a class to protobuf

This is how you can use ProtobufSourceGenerator .

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="LaDeak.ProtobufSourceGenerator" Version="1.5.1" OutputItemType="Analyzer" ReferenceOutputAssembly="true" />
		<PackageReference Include="protobuf-net" Version="3.2.26" />
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using ProtoBuf;
using ProtobufSourceGeneratorDemo;

using var ms = new MemoryStream();
Serializer.Serialize(ms,new Person() { Name= "Andrei Ignat" });
ms.Seek(0,SeekOrigin.Begin);
var entity = Serializer.Deserialize<Person>(ms);
Console.WriteLine("name is "+entity.Name);

using ProtoBuf;

namespace ProtobufSourceGeneratorDemo;

[ProtoContract]
public partial class Person
{
    
    public int Id { get; set; }
    public string? Name { get; set; }
}

The code that is generated is

// <auto-generated/>
#nullable enable
namespace ProtobufSourceGeneratorDemo;
[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute]
public partial class Person
{
    [global::ProtoBuf.ProtoMember(1)]
    private int ProtoId { get => Id; set => Id = value; }

    [global::ProtoBuf.ProtoMember(2)]
    private string? ProtoName { get => Name; set => Name = value; }
}
