Aspire.Hosting.Azure.CognitiveServices 8.1.0

Aspire.Hosting.Azure.CognitiveServices library

Provides extension methods and resource definitions for a .NET Aspire AppHost to configure Azure OpenAI.

Getting started

Prerequisites

• Azure subscription - create one for free

Install the package

In your AppHost project, install the .NET Aspire Azure Hosting Cognitive Services library with NuGet:

dotnet add package Aspire.Hosting.Azure.CognitiveServices

Configure Azure Provisioning for local development

Adding Azure resources to the .NET Aspire application model will automatically enable development-time provisioning for Azure resources so that you don't need to configure them manually. Provisioning requires a number of settings to be available via .NET configuration. Set these values in user secrets in order to allow resources to be configured automatically.

{
    "Azure": {
      "SubscriptionId": "<your subscription id>",
      "ResourceGroupPrefix": "<prefix for the resource group>",
      "Location": "<azure location>"
    }
}

NOTE: Developers must have Owner access to the target subscription so that role assignments can be configured for the provisioned resources.

Usage example

Then, in the Program.cs file of AppHost, add an Azure OpenAI service and consume the connection using the following methods:

var openai = builder.AddAzureOpenAI("openai");

var myService = builder.AddProject<Projects.MyService>()
                       .WithReference(openai);

The WithReference method passes that connection information into a connection string named openai in the MyService project. In the Program.cs file of MyService, the connection can be consumed using the client library Aspire.Azure.AI.OpenAI:

builder.AddAzureOpenAIClient("openai");
