问题:

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)\packages\xunit.runners.1.9.1\tools), 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.

Be sure to search Including Prereleases. The package you need is 'xUnit.net [Visual Studio Runner]', which is a prerelease. If you only search for Stable releases, you will only find 'xUnit.net: Runners', which will not work in Visual Studio.
