Output from F# printfn displays line breaks after every character

[lawrencecraft]

Output from F#'s printfn is displayed with a newline after every character. See screenshots attached.

Sample code:

module tests
open NUnit.Framework

[<Test>]
let ``Output test``() = 
    System.Console.WriteLine("System.Console.WriteLine")
    printfn "printfn"

Results:

This does not appear in the NUnit GUI:

The same issue does not appear for printfn output from MsTest.

I'm using Visual Studio 2012 on Windows 7.

I suspect this goes beyond F#. What happens if you replace the WriteLine by a series of Writes of one char followed by a final WriteLine()?

[lawrencecraft]

Good point--the following code prints a string char-by-char and exhibits the same behavior.

[<Test>]
let ``Single char output test``() = 
    "testing" |> Seq.iter System.Console.Write

That might be the issue--it appears to add \r after every output line it receives?

Yes, that's what I thought too. Should be an easy fix.

@OsirisTerje I moved this from the 3.0-only milestone. Why didn't you think it should be fixed in 2.x?
