It would be nice to have TryParse support for BsonDocument instead of just the Parse method which throws an exception.

For example, the current way to parse a string:

BsonDocument document = BsonDocument.Parse("{}");

If this fails it throws an exception. However most of the .NET framework now supports a less heavy check, for example:

BsonDocument document;

if (!document.TryParse("{}",out document))
{
    // Handle failed parse
}
