Remarks

This is the shape of MapAsync. A projection continues after each version of its input, thus other code must release it and a GC cannot collect it. An object in a projection can hold resources, and the callback that releases one object at an eviction does not run for the objects that the projection holds at its end.

Bind to Items, and put this object with the other resources of the caller.

This is a class, as the status of MapAsync is. A copy of it is the same projection and not a second handle to dispose, and no default value exists whose disposal throws.

Properties

Items

One object per key, in the collection's order.

Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
