System.Threading.Extensions (nuget): This library provides interfaces and implementations for Task- and Filesystem operations. It ships implementations which can be used in unit testing, 	for example to achieve deterministic scheduling when writing tests involving tasks, timers. Furthermore, it ships an implementation which implements an InMemoryFileSystem 	which can be used to write unit tests for classes which interact with the filesystem, without involving any disk I/O, thus speeding up tests and improving isolation 	of unit tests from failures / parallel executions.
