## What it is
The official, strongly-typed .NET client library for Elasticsearch, maintained by Elastic. It provides typed requests and responses for Elasticsearch APIs and delegates transport concerns like connection pooling and retries to Elastic.Transport.

## Use cases
- query elasticsearch from a c# application
- index and search documents in elasticsearch using .net
- official elasticsearch client for dotnet
- strongly typed elasticsearch api requests in c#
- connect .net app to elastic cloud
- manage elasticsearch indices from c# code

## When to choose
- you are building a .NET application that talks to Elasticsearch
- you want an officially supported client with strongly typed requests and responses
- you need compatibility with Elasticsearch 8.x/9.x from C#

## When to avoid
- you use a language other than C#/.NET
- you need strict semantic versioning, since the client follows Elasticsearch versioning with possible breaking changes
- you need backward compatibility with earlier Elasticsearch major versions

## Facets
- artifact type: library

- domain: databases, developer-tools, apis
- platform: dotnet, c, cross-platform
