Connection times out after upgrading MongoDB.Driver from 2.7.0 to 2.7.1

Question

I am using a MongoDB v3.6.2 instance on Docker in my local dev environment. Upgrading the MongoDB.Driver NuGet package from 2.7.0 to 2.7.1 makes the following code throw an exception.

string connectionString = "mongodb://localhost:27017/foo";
var database = new MongoClient(connectionString).GetDatabase("foo");
var collections = database.ListCollectionNamesAsync().Result.ToListAsync().Result;

I expect the list of collection as always, but the following exception is thrown instead.

System.AggregateException: One or more errors occurred.

This was running on an Ubuntu 18.06 x64 machine with .NET SDK v2.1.403.

Answer 1

I know this isn't an answer, but I lack the reputation points to comment. I am also having this same problem. This morning I updated my driver to 2.7.1. I don't see the problem in Windows, but I do see the problem when running my application in a linux docker container.

Update: 2.7.2 was published, and it fixed the problem for me.

Answer 2

I had same problem. They have just published 2.7.2. And it resolved.
