#r "nuget: FSharp.Data"
type TP = FSharp.Data.CsvProvider< @"C:\Temp\multiline.csv", InferRows = 2>

multiline.csv:

f1,f2
"multi-
line field",2

Error:

Error: input.fsx (1,11)-(1,76) typecheck error The type provider "ProviderImplementation.CsvProvider" reported an error: Cannot read sample CSV from 'C:\Temp\multiline.csv': Couldn't parse row 1 according to schema: Expected 2 columns, got 1

In the sample, one row of data occupies two lines of the file. InferRows pre-truncates file lines, not data rows:
