Why Frame.X static methods from Deedle are generating warnings in VS 2017?

Question

I downloaded the new VS 2017 yesterday and it is working fine, except that I am getting this warning on every line where I call the static method Frame.ReadCsv

Answer 1

It seems you have to use ReadCsv(path="file.csv") instead of ReadCsv(location="file.csv"). The first case provides you with an interface that has option values for optional settings instead of nullables, and addresses the correct overload.
