Hey @AtwoodTM I know it took a while, but thanks for reporting this. Yes indeed the correct code is:

Target.create "Generate Reports" (fun _ ->
  !! "**/opencover.xml"
  |> Seq.toList
  |> ReportGenerator.generateReports (fun p -> { p with TargetDir = "c:/reports/" })
)

For some reason that module takes a list and inference in F# is not strong enough to figure out the types when defining the function as in the docs (a type hint would be required) :(
In any chase I changed it to a sequence in the next version and changed the docs.
