How to install the low-level .NET client for Elasticsearch
The dependency-free low-level .NET client for Elasticsearch is
ElasticLowLevelClient. It has a few conventions, mainly; it takes post data and uses it to send data.
Just so that you know, the other .NET client is a high-level NEST client called
ElasticClient. It’s used for mapping document IDs, naming properties, and index names, to name a few. It is also JSON .NET dependent. We won’t focus on the high-level client for now.
This tutorial shows you step-by-step how to install low level .net client Elasticsearch. The
ElasticLowLevelClient let’s you can post or send a group of
string or even
object, and then Elasticsearch will use a special format to serialize it. With Elasticsearch’s low-level .NET client, you’ll be able to post a
byte array or pass an object and the special conversion formatting still applies in those cases. Consistent and reliable describes the low-level .NET client for Elasticsearch.
.NET Core – Install .NET SDK and the .NET Core Runtime environment. They’re available for macOS, Windows, and Linux platforms.
Elasticsearch – To work with the .NET, you must have Elasticsearch v5 or a higher version. As a rule, download the latest version.
Install the library using the NuGet Package Manager Console.
.NET Core SDK and .NET Runtime Downoad and Installation Instructions for the macOS Platform
After downloading the .NET core SDK and .NET runtime for macOS, install both environments on the macOS platform.
This image shows where you would access the required downloads for the macOS platform from the Microsoft Dot Net Download page.
.NET Core SDK and .NET Runtime Download and Installation Instructions for Debian-based Platform
Install the .NET Core SDK and .NET runtime environments for Debian in this way:
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install aspnetcore-runtime-2.2
Alternatively, visit Microsoft’s .NET download website and download and install the environments for platform manually. It will require that you register the Microsoft key prior to downloading. From the downloads page, click the arrow under Linux Distribution to register the Microsoft key for your environment. Options include CentOS/Oracle, Debian, Fedora, RHEL, Open SUSE Leap, SLES, and Ubuntu.
After you register the Microsoft key, download packages repository
If you haven’t already registered the Microsoft key from your download, do so and then you can downloaded the packages repository.

Next, install Linux’s
.deb package repository for Microsoft products:
Install the .Net Core SDK for the Linux platform:
Here’a an example of the .Net client package installation for Ubuntu.

Instructions for installing the NET Low-Level Client for Elasticsearch
Before you begin, run the programs to verify that you’ve downloaded and installed the .NET Core SDK correctly.
Below is an example of the .NET version on a macOS platform.
In Visual Studio, now you can open a document you created previously if you want to use it with Elasticsearch’s low-level .Net client. However, I recommend that you create a new test project first.
Double-click the Packages folder, and then select “Elasticsearch.net” package from the list. Click “Add Package” to install it.
The image below shows Visual Studio and the Elasticsearch.NET package option.
You’ve done it! Elasticsearch.NET low-level client is on your operating platform.
Elasticsearch uses two .NET clients. A high-level .NET NEST client that is dependent on third-party JSON .NET. It is responsible for mapping and inferences for many document-naming conventions. It gets much praise.
However, this tutorial focused on the other low-level client, which is free of dependents. Today you learned how to install low level .NET client Elasticsearch, the
ElasticLowLevelClient. It has fewer conventions in number, yet handles important functions.
