Support GetFileInfo for directories

[aspnet-hello]

From @stilettk on Friday, November 3, 2017 2:56:28 AM

Currently GetFileInfo supports only files: when called on a path that points to a directory it returns PhysicalFileInfo which has IsDirectory == false.

So, when given a path, how to decide what to do: to call GetFileInfo (if it's a file) or call GetDirectoryContents (if it's a folder)? Currently the only way I found isn't very intuitive:
bool isDirectory = fileProvider.GetDirectoryContents(myPath).Exists

My suggestion:
new PhysicalFileProvider(myPath).GetFileInfo("data")
Expected:
PhysicalDirectoryInfo
Actual:
PhysicalFileInfo

Hello!
What's the resolution? Is it works as designed?

[muratg]

@stilettk Do you have any specific scenario broken?

[stilettk]

@muratg No, it was just a suggestion. I was confused because no label was assigned and the close reason was not clear. Anyway, I think I got it now: "no further action is planned for this issue" seems to refer to "won't fix".

@stilettk Ah, got it 👍

I've also run into this while working on aspnet/AuthSamples#28. It's not blocking but it is confusing and inconvenient.

So no change will happen on it?
I'm trying to use the FileProviders as source to query for a file-explorer and GetFileInfo returning wrong informations for directories.
