hi

It may be that different environments use wrong appsettings.json.

Hi @maliming, I thought about that at first, so I have set the "IsEnabled": "false" for all the setting files, I also tried to delete all the appsettings and left the appsetings.json -> also got the same issue

I tested again in my localhost with deployment in IIS, the same issue happens. It only works fine if we run it on IIS Express using visual studio.

Hi there,

The problem is that abp platform forces to use Redis in production mode. I belive this is a bug, or there is something else on that. Commenting lines are solved this issue for me (see the code below).

    private void ConfigureRedis(
        ServiceConfigurationContext context,
        IConfiguration configuration,
        IWebHostEnvironment hostingEnvironment)
    {
        if (!hostingEnvironment.IsDevelopment())
        {
            /*var redis = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]);
            context.Services
                .AddDataProtection()
                .PersistKeysToStackExchangeRedis(redis, "edelivery2-Protection-Keys");*/
        }
    }

hi jurec

The tiered project needs the Redis.

Hi @maliming, why redis is mandatory for tiered project? this is not mentioned in the documentation:

https://docs.abp.io/en/abp/latest/Redis-Cache

if it is because of key storage provider, we can replace it by entity framework core, right?

https://docs.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/key-storage-providers?view=aspnetcore-5.0&tabs=visual-studio

please help check and confirm.

why redis is mandatory for tiered project?

Applications are using caching, such as caching query results, settings, permissions, etc., so we need to cache, especially tiered project.

Hi @maliming, is it for performance purpose only? what if we are using tiered project and do not install the redis? I have replaced the data protection storage provider with EF core.

If you don't use redis, the caches of multiple projects will be inconsistent and cause problems.
