Describe the bug
MockFile.ReadAllText throws NullReferenceException on non existing file. I expect FileNotFoundException

To Reproduce

fileSystem.File.ReadAllText("nonexisting file", Encoding.UTF8);
--> A NullReferenceException is thrown

Expected behavior
--> A FileNotFoundException is thrown

Thanks for reporting!

I can't reproduce this issue: the given code snippet produces the expected behaviour.

Also there's already a test that ensures it:
MockFile_ReadAllLines_NotExistingFile_ThrowsCorrectFileNotFoundException

It was added by #427

@derpflanz Could you please verify with the latest version? If the issue still occurs could you provide some more information about your environment?

@fgreinacher I tried to find the sport and reproduce, but it has been a few months and our code continued to evolve :).

It seems like it works fine, so I guess an update fixed it.

Thanks for checking again, I guess we can close this then.
