Connection failing in startup.cs

[ms-mansisinghal]

Hi,

I am trying the following code in my startup.cs to make the connection for redis cache but it isn't working for me.

            services.AddStackExchangeRedisCache(async options =>
            {
             
                 var configurationOptions = await ConfigurationOptions.Parse($"{CacheName}:6380").ConfigureForAzureWithSystemAssignedManagedIdentityAsync(principalID);
                 options.ConfigurationOptions = configurationOptions;
                 var connectionMultiplexer = ConnectionMultiplexer.ConnectAsync(configurationOptions);
                
                options.InstanceName = Constants.UserManagementService;

            });

Can someone provide a sample for this or managed identity in startup.cs

Have you seen the sample code in this Repo for connecting with Service principal? What error you are getting? https://github.com/Azure/Microsoft.Azure.StackExchangeRedis/blob/main/sample/Sample.cs#L66

Hello, could you update with the error and where you're running the startup.cs? Connecting with AAD is only supported on Azure VMs for now.

Hey, we are trying to connect our Reddis cache to an Azure App service. Is that possible?
Our goal is to switch to managed identity so we followed the steps on this link
And I am not able to see the error in the logs but the API calls based on this redis are failing.
I have updated the managed Identity code. Tried this and Service principal as well.

It seems this library does not work together with ASP.NET Core's Microsoft.Extensions.Caching.StackExchangeRedis extensions. Is there anything in progress to get this working?

Please show a sample using ASP.NET Core Web App.

The extension built out of this repo is only for the StackExchange.Redis library itself. To request AAD support for Microsoft.Extensions.Caching.StackExchangeRedis, I'd recommend creating an issue in the https://github.com/dotnet/aspnetcore repo.

@sven5 - we were able to get Microsoft.Azure.StackExchangeRedis working with Microsoft.Extensions.Caching.StackExchangeRedis, adding Entra auth to our Redis resources via an extension method and still using IDistributedCache

csproj:

<PackageReference Include="Microsoft.Azure.StackExchangeRedis" Version="3.1.0" />
<PackageReference Include="Microsoft.Extensions.Caching.StackExchangeRedis" Version="8.0.7" />

Extension method:


public static class CachingExtensions
{
    public static async Task<IServiceCollection> AddCaching(this IServiceCollection services, IConfiguration configuration)
    {
        services.Configure<CachingOptions>(configuration.GetSection(CachingOptions.Position));
        var settings = configuration.GetSection(CachingOptions.Position).Get<CachingOptions>(); 
        
        var configurationOptions = ConfigurationOptions.Parse(settings.RedisConnectionString);
        await configurationOptions.ConfigureForAzureWithTokenCredentialAsync(new DefaultAzureCredential());
        configurationOptions.DefaultDatabase = settings.RedisDefaultDatabase;
        
        services.AddStackExchangeRedisCache(options =>
        {
            options.ConfigurationOptions = configurationOptions;
        });       

        return services;
    }
}

Program.cs (minimal):

var builder = WebApplication.CreateBuilder(args);

await builder.Services.AddCaching(builder.Configuration);
