Create a RedisConnectionProvider instance and add it to the DI container.

RedisOMConfig.cs

public static void AddRedisOMConnectionProvider(this WebApplicationBuilder webApplicationBuilder)
{
    var host = webApplicationBuilder.Configuration.GetSection("Redis")["Host"];
    var port = webApplicationBuilder.Configuration.GetSection("Redis")["Port"];
    var redisConnectionConfiguration = new RedisConnectionConfiguration
    {
        Host = host,
        Port = Convert.ToInt32(port)
    };
    var redisConnectionProvider = new RedisConnectionProvider(redisConnectionConfiguration);
    webApplicationBuilder.Services.AddSingleton(redisConnectionProvider);
}
