Add the given attributes to this IGraphTShape. Further calls to WithAttributes(Attributes) will not remove these attributes. Note that this operation has no effect on an empty Flow (because the attributes apply only to the contained processing stages).

Put an asynchronous boundary around this Graph.

TBD

Add a name attribute to this Graph.

Change the attributes of this IGraphTShape to the given ones and seal the list of attributes. This means that further calls will not be able to remove these attributes, but instead add new ones. Note that this operation has no effect on an empty Flow (because the attributes apply only to the contained processing stages).
