I used only one slave server in connection settings from the configured replica set:
rs.status()
{
"myState" : 2,
"members" : [
{ "name" : "localhost:31500", "state" : 1, "stateStr" : "PRIMARY", ... },
{ "name" : "localhost:31502", "state" : 7, "stateStr" : "ARBITER", ... },
{ "name" : "localhost:31501", "state" : 2, "stateStr" : "SECONDARY", ... } ], ...
}
Test code:

var client = new MongoClient(new MongoClientSettings { ConnectionMode = ConnectionMode.Automatic, Servers = new []{ MongoServerAddress.Parse("localhost:31501")} }); var result = client.GetDatabase("test").RunCommand<BsonDocument>(new BsonDocument() { { "connectionStatus", 1 } });
I get an exception:
System.TimeoutException: A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = ReadPreferenceServerSelector{ ReadPreference = { Mode = Primary, TagSets = [] } }, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }.

But if you specify another server name, the connection is established.

But it does not work if I connect to a single server:
- localhost:30000 - standalone

How to connect with automatic mode to a variable number of servers?
