var database = mongoClient.GetDatabase("DB_NAME");
var collection = database.GetCollection<Collection>("COLLECTION_NAME");

Filter

Cs.svg
var builder = Builders<MyClass>.Filter;
FilterDefinition<MyClass> filter = filterDefinition.Empty;

filter &= builder.Eq(x => x.Property1, "id");
filter &= builder.In(x => x.Property1, new[] { "id1", "id2" });  // filter by Property1 equals to one of the ids

var result = (await collection.FindAsync(filter)).ToList();

Log

var mongoUrl = new MongoUrl("MONGODB_CONNECTION_STRING");
var mongoClientSettings = MongoClientSettings.FromUrl(mongoUrl);
mongoClientSettings.ClusterConfigurator = cb =>
{
    cb.Subscribe<CommandStartedEvent>(e =>
    {
        logger.LogTrace($"{e.CommandName} - {e.Command.ToJson()}");
    });
};
this.mongoClient = new MongoClient(mongoClientSettings);
