ducker installed and the container is working...

System.TimeoutException: 'A timeout occurred after 30000ms selecting a server using CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }.

the issue in getting the value by IConfiguration interface from the "appsettings.json"

  "DatabaseSettings": {
    "ConnectionString": "mongodb://localhost:27017",
    "DatabaseName": "CatalogDb",
    "CollectionName": "Products"
  },

if I add this code:

            var clientTxt = configuration.GetValue<string>("DatabaseSettings:ConnectionString");
            var databasTxt = configuration.GetValue<string>("DatabaseSettings:DatabaseName");
            var producTxt = configuration.GetValue<string>("DatabaseSettings:CollectionName");
            Console.Write($"client: {clientTxt} \ndatabase: {databasTxt} \nproduct {producTxt}");

I will get

client: mongodb://catalogdb:27017
database: ProductDb
product Products
