editThis page shows you how to install the .NET client for Elasticsearch.
The v8 client for .NET does not have complete feature parity with
the v7 NEST client. It may not be suitable for for all applications until
additional endpoints and features are supported. We therefore recommend you thoroughly
review our release notes before attempting to migrate
existing applications to the Elastic.Clients.Elasticsearch library.
Until the new client supports all endpoints and features your application requires,
you may continue to use the 7.17.x NEST client
to communicate with v8 Elasticsearch servers using compatibility mode. Refer to the
Connecting to Elasticsearch v8.x using the v7.17.x client documentation
for guidance on configuring the 7.17.x client.
Installing the .NET client
editFor SDK style projects, you can install the Elasticsearch client by running the following .NET CLI command in your terminal:
dotnet add package Elastic.Clients.Elasticsearch
This command adds a package reference to your project (csproj) file for the latest stable version of the client.
If you prefer, you may also manually add a package reference inside your project file:
<PackageReference Include="Elastic.Clients.Elasticsearch" Version="{latest-version}" />
NOTE: The version number should reflect the latest published version from NuGet.org. To install a different version, modify the version as necessary.
For Visual Studio users, the .NET client can also be installed from the Package Manager Console inside Visual Studio using the following command:
Install-Package Elastic.Clients.Elasticsearch
Alternatively, search for Elastic.Clients.Elasticsearch in the NuGet Package
Manager UI.
To learn how to connect the Elasticsearch client, refer to the Connecting section.
Compatibility
editThe Elasticsearch client is compatible with currently maintained .NET runtime versions. Compatibility with End of Life (EOL) .NET runtimes is not guaranteed or supported.
Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of Elasticsearch. Elasticsearch language clients are only backward compatible with default distributions and without guarantees made.
Refer to the end-of-life policy for more information.
CI feed
editWe publish CI builds of our client packages, including the latest unreleased features. If you want to experiment with the latest bits, you can add the CI feed to your list of NuGet package sources.
Feed URL: https://f.feedz.io/elastic/all/nuget/index.json
We do not recommend using CI builds for production applications as they are not formally supported until they are released.
