In F# unit test project targeting net462 & referencing mstest v2 latest nuget.
Code:

namespace ns
open Microsoft.VisualStudio.TestTools.UnitTesting
open Swensen.Unquote
[<TestClass>]
type ``Liquid Crystal (LC) Calibration process tests``() =
    
    [<TestMethod>]
    member __.``Test Method``() =
        test <@ true @>


that (LC) thing causes NullReferenceException

Hi, thanks for sharing this problem.

I think I can see how this could come about. It's caused by a hole in NCrunch's support for methods/classes that contain brackets in their names. In most .NET based languages, it isn't possible to create these, though F# seems to be the exception. I'll make a note to see if we can introduce a fix for this. For the time being, I recommend renaming the test class.
