+In the preview [.NET SDK](https://www.nuget.org/packages/Azure.Search.Documents/11.5.0-beta.1) for Azure Cognitive Search, you can use the following syntax to create an index alias. 
+
+```csharp
+// Create a SearchIndexClient
+SearchIndexClient adminClient = new SearchIndexClient(serviceEndpoint, credential);
+
+// Create an index alias
+SearchAlias myAlias = new SearchAlias("my-alias", "hotel-quickstart-index");
+adminClient.CreateAlias(myAlias);

 If you expect that you may need to make updates to your index definition for your production indexes, you should use an alias rather than the index name for requests in your client-side application. Scenarios that require you to create a new index are outlined under these [rebuild conditions](search-howto-reindex.md#rebuild-conditions).

-> You can only use an alias with [document operations](/rest/api/searchservice/document-operations). Aliases can't be used to get or update an index definition, can't be used with the Analyze Text API, and can't be used as the `targetIndexName` on an indexer.
