How do I do I execute tests in Debug mode using .Net Core and VSCode?

Question

How do I execute tests in Debug mode using .Net Core and VSCode?

I am currently running the following on the command line:

dotnet Test

However, this is not executing the tests in debug mode.

Do I attach a debugger?

If so... How?

Does your use case require running the tests from the command line, or are you open to running the tests from VSCode? — Shaun Luttin, Aug 05 '17 at 21:13
I'm open to running tests from VSCode. 2.0.0-preview3-006887 — Scott Nimrod, Aug 05 '17 at 21:46
Does your use case require running *all* the tests at once, or are you open to running one test at a time in debug mode? — Shaun Luttin, Aug 05 '17 at 21:55
It appears that VSCode does not support F# debugging at this time. See https://github.com/ionide/ionide-vscode-fsharp/issues/387 and https://github.com/ionide/ionide-vscode-fsharp/issues/408 — Shaun Luttin, Aug 06 '17 at 00:18
Do you need to use a debugger or do you need to run the tests under a debug configuration? — Shaun Luttin, Aug 06 '17 at 00:19
For what it is worth... I use xUnit, .NET Core, F#, VS Code. The xUnit template includes a Main function. The "dotnet test" ignores that function. But, I can call one of the tests from the Main function... and press F5 to step through it. That's what I'm doing. — Wallace Kelly, Aug 09 '17 at 00:28
Our C# friends currently have a convenient "debug test" link that appears in the VS Code editor: https://stackoverflow.com/questions/38146011 — Wallace Kelly, Aug 10 '17 at 16:40

If necessary, convert the test project to be a console app, instead of a library. For example, use

<TargetFramework>netcoreapp2.0</TargetFramework>

    // C#
    class Program
    {
        static void Main(string[] args)
        {
        }
    }

    // F#
    module Program =
        [&ltEntryPoint&gt]
        let main(args: string[]) = 0

This should have no effect on running dotnet test.

I didn't have to convert the Test project to a Console. I just added a main function. – Scott Nimrod Aug 10 '17 at 15:44
@ScottNimrod What is the TargetFramework of your project? – Wallace Kelly Aug 10 '17 at 15:45
