CodeMaze have written a great post with real world examples of using C# and DalSoft.RestClient to consume any REST API. It includes everything you need to know head over there now if you find yourself writing a lots of boilerplate code to consume REST API’s.

Before 3.3.1 if you wanted to control serialization you would have to decorate your model with attributes, for example if your REST API used snake case naming convention:

public class User
{
  [JsonProperty("phone_number")]
  public string PhoneNumber { get; set; }
}

As of 3.3.1 you can provide JsonSerializerSettings to the config – this saves you having to add the attributes to properties individually, which will make your code cleaner. For example if your REST API used snake case naming convention:

// When directly creating a RestClient instance
dynamic restClient = new RestClient("https://dalsoft.co.uk", new Config()
	.SetJsonSerializerSettings(new JsonSerializerSettings { ContractResolver =  new DefaultContractResolver { NamingStrategy = new SnakeCaseNamingStrategy() } }));

// When using IHttpClientFactory
 services
	.AddRestClient(Name, "https://dalsoft.co.uk")
	.SetJsonSerializerSettings(new JsonSerializerSettings { ContractResolver =  new DefaultContractResolver { NamingStrategy = new SnakeCaseNamingStrategy() } });

Now the SnakeCaseNamingStrategy ContractResolver is used by default when deserializing responses from your REST API.

I recently needed to use Twitter’s API along with it’s OAuth 1.0 implementation in .NET Core. As part of this work I created a DalSoft.RestClient Handler, and released it as a full SDK.

Prior to .NET Core 2.1 anyone who has tried to use HttpClient at scale (maybe from a microservice) may have run into the dreaded socket exhaustion issue.

Socket exhaustion happens because HttpClient is designed to be instantiated once and re-used throughout the life of an application, if you make HTTP calls in a server application for every request you will run out of sockets (because sockets get left in TIME_WAIT state for 240 seconds by default).

Using IHttpClientFactory can improve performance by 43%!

Recently I’ve been playing around with Entity Framework Core and it’s been a great positive experience overall, however as I started to port one of my projects over I fell foul of the lack of Seeding support. For those that haven’t used the Seed functionality in EF 6, it’s basically a method to populate the database with data that is invoked when migrations finish. There is a open GitHub issue regarding seeding support in EF Core.

My requirements are simple I’d like to use the dotnet CLI to run environment specific Migrations and Seeding from my continuous deployment pipeline. In this post I’m going to show you how I got environment specific Migrations and Seeding working. There are a couple of things that work differently that we need to workaround but that’s fine.
