Aspire.Hosting.Azure.SignalR 8.1.0

Aspire.Hosting.Azure.SignalR library

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

Getting started

Prerequisites

• Azure subscription - create one for free

Install the package

Install the .NET Aspire Azure SignalR Hosting library with NuGet:

dotnet add package Aspire.Hosting.Azure.SignalR

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

In the Program.cs file of AppHost, add a SignalR connection and consume the connection using the following methods:

var signalR = builder.AddAzureSignalR("sr");

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

The WithReference method configures a connection in the MyService project named sr. In the Program.cs file of MyService, the Azure SignalR connection can be consumed using the client library Microsoft.Azure.SignalR:

builder.Services.AddSignalR()
    .AddNamedAzureSignalR("sr");
