SDK samples
Code samples from the Azure SDK development team demonstrate API usage. You can find these samples on GitHub.
| Sample | Description |
|---|---|
| Hello world - synchronous | Demonstrates how to create a client, authenticate, and handle errors using synchronous methods |
| Hello world - asynchronous | Demonstrates how to create a client, authenticate, and handle errors using asynchronous methods |
| Service-level operations | Demonstrates how to create indexes, indexers, data sources, skillsets, and synonym maps. This sample also shows you how to get service statistics and how to query an index |
| Index operations | Demonstrates how to perform an action on existing index, in this case getting a count of documents stored in the index |
| FieldBuilderIgnore | Demonstrates a technique for working with unsupported data types |
| Indexing documents (push model) | Push model indexing, where you send a JSON payload to an index on a service |
| Encryption key sample | Demonstrates using a customer-managed encryption key to add an extra layer of protection over sensitive content |
| Vector search sample | Shows you how to index a vector field and perform vector search using the Azure SDK for .NET |
| Semantic ranking sample | Shows you how to configure semantic ranker in an index and invoke semantic queries using the Azure SDK for .NET |
Doc samples
Code samples from the Azure AI Search team demonstrate features and workflows. All of the following samples are referenced in tutorials, quickstarts, and how-to articles that explain the code in detail.
