.NET JsonContent for HttpClient

.NET already comes with a nice collection of HttpContent serializers, but it lacks a JsonContent type. A common solution is to just serialize their payload to a JSON string and that insert that into an instance of StringContent. However, this means that you need to remember to set your headers, and it is a little bit inefficient because of how it creates multiple strings and buffers for each payload.

I have create a simple implementation of JsonContent that uses Json.NET and pooled memory streams. The result is between 2% and 10% faster, and causes ~50% fewer garbage collections.

Check out the implementation in Tact.NET:

• Source - JsonContent.cs
• Tests - JsonContentTests.cs

Enjoy,
