Methods

	Name	Description
	AppendStageTNewResult	Appends the stage to the pipeline.
	AsTNewResult	Changes the result type of the pipeline.
	BucketTValue(AggregateExpressionDefinitionTResult, TValue, IEnumerableTValue, AggregateBucketOptionsTValue)	Appends a $bucket stage to the pipeline.
	BucketTValue, TNewResult(AggregateExpressionDefinitionTResult, TValue, IEnumerableTValue, ProjectionDefinitionTResult, TNewResult, AggregateBucketOptionsTValue)	Appends a $bucket stage to the pipeline with a custom projection.
	BucketAutoTValue(AggregateExpressionDefinitionTResult, TValue, Int32, AggregateBucketAutoOptions)	Appends a $bucketAuto stage to the pipeline.
	BucketAutoTValue, TNewResult(AggregateExpressionDefinitionTResult, TValue, Int32, ProjectionDefinitionTResult, TNewResult, AggregateBucketAutoOptions)	Appends a $bucketAuto stage to the pipeline with a custom projection.
	ChangeStream	Appends a $changeStream stage to the pipeline. Normally you would prefer to use the Watch method of IMongoCollectionTDocument. Only use this method if subsequent stages project away the resume token (the _id) or you don't want the resulting cursor to automatically resume.
	Count	Appends a count stage to the pipeline.
	FacetTNewResult	Appends a $facet stage to the pipeline.
	GraphLookupTFrom, TConnectFrom, TConnectTo, TStartWith, TAsElement, TAs, TNewResult	Appends a $graphLookup stage to the pipeline.

	Limit	Appends a limit stage to the pipeline.
	LookupTForeignDocument, TNewResult(String, FieldDefinitionTResult, FieldDefinitionTForeignDocument, FieldDefinitionTNewResult, AggregateLookupOptionsTForeignDocument, TNewResult)	Appends a lookup stage to the pipeline.
	LookupTForeignDocument, TAsElement, TAs, TNewResult(IMongoCollectionTForeignDocument, BsonDocument, PipelineDefinitionTForeignDocument, TAsElement, FieldDefinitionTNewResult, TAs, AggregateLookupOptionsTForeignDocument, TNewResult)	Appends a lookup stage to the pipeline.
	Match	Appends a match stage to the pipeline.
	MergeTOutput	Appends a merge stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
	MergeAsyncTOutput	Appends a merge stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
	OfTypeTNewResult	Appends a match stage to the pipeline that matches derived documents and changes the result type to the derived type.
	Out(IMongoCollectionTResult, CancellationToken)	Appends an out stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
	Out(String, CancellationToken)	Appends an out stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.

	OutAsync(String, CancellationToken)	Appends an out stage to the pipeline and executes it, and then returns a cursor to read the contents of the output collection.
	ProjectTNewResult	Appends a project stage to the pipeline.
	ReplaceRootTNewResult	Appends a $replaceRoot stage to the pipeline.
	ReplaceWithTNewResult	Appends a $replaceWith stage to the pipeline.
	Skip	Appends a skip stage to the pipeline.
	Sort	Appends a sort stage to the pipeline.
	SortByCountTId	Appends a sortByCount stage to the pipeline.
	ToCollection	Executes an aggregation pipeline that writes the results to a collection.
	ToCollectionAsync	Executes an aggregation pipeline that writes the results to a collection.
	ToCursor	Executes the operation and returns a cursor to the results. (Inherited from IAsyncCursorSourceTDocument.)
	ToCursorAsync	Executes the operation and returns a cursor to the results. (Inherited from IAsyncCursorSourceTDocument.)
	UnionWithTWith	Appends an $unionWith stage to the pipeline.
	UnwindTNewResult(FieldDefinitionTResult, IBsonSerializerTNewResult)	Obsolete. Appends an unwind stage to the pipeline.
	UnwindTNewResult(FieldDefinitionTResult, AggregateUnwindOptionsTNewResult)	Appends an unwind stage to the pipeline.
