Does the .net framework provides async methods for working with the file-system?

Question

Does the .net framework has an async built-in library/assembly which allows to work with the file system (e.g. File.ReadAllBytes, File.WriteA

Answer 1

In .NET core (since version 2.0) there are now all the async flavors of corresponding ReadAll/WriteAll/AppendAll methods like:

File.(Read|Write|Append)All(Text|Lines|Bytes)Async

https://docs.microsoft.com/en-us/dotnet/api/system.io.file.readallbytesasync?view=netcore-2.1

Unfortunately, they are still missing from .NET standard 2.0.
