I am trying to do some csv work in F# Referencing this page:

[https://fsprojects.github.io/FSharp.Data/library/CsvProvider.html](https://fsprojects.github.io/FSharp.Data/library/CsvProvider.html)

the samples keep using the `ResolutionFolder` bit. Would someone explain to me what it does and why it is needed?

I think it is to make the path given as the first argument relative to that folder.

I suggest not using it and instead, rely on F# construction such as `CsvProvider< const ( __SOURCE_DIRECTORY__ + "/relativepath/from/sourcecode") >`

This works in all contexts, even for type provider that wouldn’t provide separate resolution folder kind of type argument.

as usual, Tomas provides a good explination here:

I happened across this looking into something else. Posting here for future searches.

This is nice explanation, but why not allow set work dir for fsi? I think it will be right.
