Name	Description
SelectMany(IAsyncEnumerable, Func>, Func)	Projects each element of a sequence to an IAsyncEnumerable, flattens the resulting sequences into one IAsyncEnumerable sequence, and invokes a result selector function on each element therein. The index of each source element is used in the intermediate projected form of that element.
SelectMany(IAsyncEnumerable, Func>>, Func>)	Projects each element of a sequence to an IEnumerable, flattens the resulting sequences into one IAsyncEnumerable sequence, and invokes a result selector function on each element therein. The index of each source element is used in the intermediate projected form of that element.
