Question

I want to query my MongoDB collection without any filter with MongoDB .NET Driver 2.0 but I didn\'t find a way. I have the following workaround but it looks weird :D

You can't use Find without a filter.

You can however use a filter that passes everything:

var findFluent = await _fooBarCollection.Find(_ => true);

Or you can use an empty document which is equivalent:

var findFluent = await _fooBarCollection.Find(new BsonDocument());

They have also added an empty filter but it will only be available in newer versions of the driver:

var findFluent = await _fooBarCollection.Find(Builders.Filter.Empty);
