c# - xUnit v1 tests appear in xUnit GUI (xunit.gui.clr4.exe) but not VS 2012 Test Explorer

Question

I have an F# Class Library with the "xUnit.net" and "xUnit.net Runners" packages installed using NuGet. I have the following code:

module XUnitTest

open Xunit

[<Fact>]
let Test () =
    do Assert.True (1 = 2)
    ()

When I run the xUnit GUI (xunit.gui.clr4.exe, which NuGet adds to (projectdirectory)packagesxunit.runners.1.9.1ools), and load the assembly built by this project, the Test () method appears, and fails when I run it, as expected.

However, I cannot get the test to appear in VS 2012's Test Explorer, no matter how many times I rebuild, restart, etc. If I click Run All, the build output window pops up but nothing else happens.

For the heck of it I also installed the xUnit.net Extensions, though I don't believe they're necessary for what I'm trying to do. That didn't help either.

Please let me know if I can provide additional information and thank you for reading!

Pretty sure based on the to/fro that you need to install xUnit.net runner for Visual Studio 2012 VSIX extension the xUnit.net runners NuGet package as detailed on the relevant xUnit docs page.

The MSTest equivalent is built in to a standard VS install.
