Methods

	Name	Description
	First<TResult>	Returns the first document of the aggregate result.
	FirstAsync<TResult>	Returns the first document of the aggregate result.
	FirstOrDefault<TResult>	Returns the first document of the aggregate result, or the default value if the result set is empty.
	FirstOrDefaultAsync<TResult>	Returns the first document of the aggregate result, or the default value if the result set is empty.
	Group<TResult>(IAggregateFluent<TResult>, ProjectionDefinition<TResult, BsonDocument>)	Appends a group stage to the pipeline.
	Group<TResult, TKey, TNewResult>(IAggregateFluent<TResult>, Expression<Func<TResult, TKey>>, Expression<Func<IGrouping<TKey, TResult>, TNewResult>>)	Appends a group stage to the pipeline.
	Lookup<TResult>(IAggregateFluent<TResult>, String, FieldDefinition<TResult>, FieldDefinition<BsonDocument>, FieldDefinition<BsonDocument>)	Appends a lookup stage to the pipeline.
	Lookup<TResult, TForeignDocument, TNewResult>(IAggregateFluent<TResult>, IMongoCollection<TForeignDocument>, Expression<Func<TResult, Object>>, Expression<Func<TForeignDocument, Object>>, Expression<Func<TNewResult, Object>>, AggregateLookupOptions<TForeignDocument, TNewResult>)	Appends a lookup stage to the pipeline.
	Match<TResult>	Appends a match stage to the pipeline.
	Project<TResult>(IAggregateFluent<TResult>, ProjectionDefinition<TResult, BsonDocument>)	Appends a project stage to the pipeline.
	Project<TResult, TNewResult>(IAggregateFluent<TResult>, Expression<Func<TResult, TNewResult>>)	Appends a project stage to the pipeline.
	Single<TResult>	Returns the only document of the aggregate result. Throws an exception if the result set does not contain exactly one document.
	SingleAsync<TResult>	Returns the only document of the aggregate result. Throws an exception if the result set does not contain exactly one document.
	SingleOrDefault<TResult>	Returns the only document of the aggregate result, or the default value if the result set is empty. Throws an exception if the result set contains more than one document.
	SingleOrDefaultAsync<TResult>	Returns the only document of the aggregate result, or the default value if the result set is empty. Throws an exception if the result set contains more than one document.
	SortBy<TResult>	Appends an ascending sort stage to the pipeline.
	SortByDescending<TResult>	Appends a descending sort stage to the pipeline.
	ThenBy<TResult>	Modifies the current sort stage by appending an ascending field specification to it.
	ThenByDescending<TResult>	Modifies the current sort stage by appending a descending field specification to it.
	Unwind<TResult>(IAggregateFluent<TResult>, FieldDefinition<TResult>)	Appends an unwind stage to the pipeline.
	Unwind<TResult>(IAggregateFluent<TResult>, Expression<Func<TResult, Object>>)	Appends an unwind stage to the pipeline.
	Unwind<TResult, TNewResult>(IAggregateFluent<TResult>, Expression<Func<TResult, Object>>, IBsonSerializer<TNewResult>)	Obsolete. Appends an unwind stage to the pipeline.
	Unwind<TResult, TNewResult>(IAggregateFluent<TResult>, Expression<Func<TResult, Object>>, AggregateUnwindOptions<TNewResult>)	Appends an unwind stage to the pipeline.
