CsvFile.Load doesn't use current directory from system.environment

[ovatsus]

I can do this:

open System.IO
System.Environment.CurrentDirectory <- __SOURCE_DIRECTORY__
File.ReadAllLines("filename")

and it picks up SOURCE_DIRECTORY\filename

but if I do this:

CsvFile.Load "filename"

It will try to load C:\Program Files (x86)\Microsoft SDKs\F#\4.1\Framework\v4.0\filename

Hi! I'd like to help out with this, but I'm wondering if I can ask a question or two first..

I might be mistaken, but it looks like it's here that AppDomain.CurrentDomain.BaseDirectory gets selected in runtime. https://github.com/fsharp/FSharp.Data/blob/1ac5f39e7297ef386e39d68f6f73859c25867fae/src/CommonRuntime/IO.fs#L52-L57

I wonder how much code, if any, exists which relies on that behavior?

It also mentions in a comment that this base directory selection is based on standard type provider rules established here: https://github.com/fsharp/fsharpx/issues/195#issuecomment-12141785.

Like I said I'd love to help out, but I'm not sure how to proceed with those concerns, or if they're even valid.

Any thoughts?

I think the issue is that CsvFile.Load and CsvFile.Save don't go throu that piece of code like the type providers

Wouldn't it be sufficient to change AppDomain.CurrentDomain.BaseDirectory to Directory.GetCurrentDirectory()?

I also ran into this problem when starting my app with dotnet run and using relative paths there.
