Report test status in Visual Studio F# projects

Hi,

create a F# test project with a NUnit test like:

```
namespace Library1

open NUnit.Framework

[<TestFixture>]
type Class1() = 
     [<Test>]
    member this.Test1() = Assert.IsFalse true
```

Continuous Tests reports the failing test in the status bar but not in the code editor.
It would be nice if this could be fixed.
