Yes. There are async methods for working with the file system but not for the helper methods on the static File type. They are on FileStream.

So, there's no File.ReadAllBytesAsync but there's FileStream.ReadAsync, etc. For example:

byte[] result;
using (FileStream stream = File.Open(@"C:\file.txt", FileMode.Open))
{
    result = new byte[stream.Length];
    await stream.ReadAsync(result, 0, (int)stream.Length);
}
