Using MsgPack in your asp.net core webapi

MsgPack (here) is reportedly faster then msgpack-cli in terms of performance. To get your excited, check out the diagram below :-

Yes, it is ridiculously fast and beat protobuf in many ways. I was gonna put on my hardworking cap and write up some formatters but this way is easier to do :-


Client code 

Client side code to de-serialized it.

	using MessagePack;
	using System;
	using System.Net.Http;
	using System.Net.Http.Headers;
	using System.Threading.Tasks;
	namespace Alphacert.Acc.Ods.Client
	{
	class Program
	{
	static async Task Main(string[] args)
	{
	Console.WriteLine("Hello World!");
	var client = new HttpClient
	{
	BaseAddress = new Uri("http://localhost:5050")
	};
	client.DefaultRequestHeaders.Accept.Clear();
	client.DefaultRequestHeaders.Accept.Add(
	new MediaTypeWithQualityHeaderValue("application/x-msgpack"));
	var result = await client.GetAsync("/ODSData/valuationsdata?version=1&last-modified=1");
	var bytes = await result.Content.ReadAsByteArrayAsync();
	var returnValueType = MessagePackSerializer.Deserialize<ViewValuation>(bytes);
	Console.WriteLine(returnValueType.GetType().Name);
	Console.WriteLine(returnValueType?.PortfolioId);
	}
	}
	}

Install

Install it through nuget using the following command :-

Install-Package WebApiContrib.Core.Formatter.MessagePack -Version 2.0.0


Next, you gotta decorate your objects with the correct attributes.

	[MessagePackObject]
	public class ViewValuation
	{
	[Key(0)]
	public string InstrumentId { get; set; }
	[Key(1)]
	public string FundKey { get; set; }
	[Key(2)]
	public string PortfolioId { get; set; }
	[Key(3)]
	public decimal? GrossMarketValueBase { get; set; }
	[Key(4)]
	public DateTime ModifiedAt { get; set; }
	}

And then somewhere in your controller, you can serialize your object as bytes and push it through using code below :-

	var path = Path.Combine(AppConstant.fileResourceFolder, AppConstant.fileResourceName);
	if (System.IO.File.Exists(path))
	{
	var result = MessagePackSerializer.Serialize(new ViewValuation() { PortfolioId = "00000" });
	return File(result, "application/x-msgpack");
	}
	else
	{
	return Accepted(); //not ready
	}
