TextResponse.ContinueAsync() Method

Initiates an asynchronous continuation task.

Namespace: DevExpress.AIIntegration.Extensions

Assembly: DevExpress.AIIntegration.v24.2.dll

NuGet Package: DevExpress.AIIntegration

Declaration

C#

public Task ContinueAsync()

VB.NET

Public Function ContinueAsync As Task

Returns

Type	Description
Task	The task.

Remarks

AI-poweredextensions automatically split large content into manageable chunks. Use the ContinueAsync method to start processing the next chunk asynchronously.

The following example registers an Azure OpenAI client and implements the Translate method. This method can manage large text blocks.
