Print to a string without sprintf

In A Peek into F# 4.1, the author demonstrated we could print to a string without sprintf:

let private tryParseWith tryParseFunc (s : string) =
    match (tryParseFunc s) with
    | true, x -> Ok x
    | false, _ -> Error ("%s is not capable of being parsed." s)

Can I not use sprintf because the compiler is smart to infer StringFormat<string> type and evaluate the expression to string value in F# 4.1 and newer?

String interpolation is currently not a feature that can be found in F# (as of version 4.1).

See https://github.com/fsharp/fslang-design/blob/master/RFCs/FS-1001-StringInterpolation.md for the current string interpolation proposal.
