C#, visual studio code, debugger, Error processing 'configurationDone' request. Unknown Error: 0x89720010,

Question

Has anyone seen this particular Visual Studio Code error, when using the debugger? I have narrowed it down to this error code, and there does not appear to be any online resource on this issue.

I am using Visual Studio Code to do some C# debugging. And it is narrowed down to this issue. I have a simple piece of code in a XUNIT project like this:

using System;
using Xunit;

namespace xunitexample
{
    public class UnitTest
    {
        [Fact]
        public void Test1()
        {
            Console.WriteLine("Hello World...");
        }
    }    
}

The project file xunitexample.csproj:

<Project Sdk="Microsoft.NET.Sdk">

<PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>

<ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
    <PackageReference Include="xunit" Version="2.2.0" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />
</ItemGroup>

The launch.json is:

{
// Use IntelliSense to find out which attributes exist for C# debugging
// Use hover for the description of the existing attributes
// For further information visit https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md
"version": "0.2.0",
"configurations": [
    {
        "name": ".NET Core Launch (console)",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "test",
        // If you have changed target frameworks, make sure to update the program path.
        "program": "${workspaceRoot}/bin/Debug/netcoreapp1.1/xunitexample.dll",
        "args": [],
        "cwd": "${workspaceRoot}",
        // For more information about the 'console' field, see https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md#console-terminal-window
        "console": "internalConsole",
        "stopAtEntry": false,
        "internalConsoleOptions": "openOnSessionStart"
    },
    {
        "name": ".NET Core Attach",
        "type": "coreclr",
        "request": "attach",
        "processId": "${command:pickProcess}"
    }
]

}

and the tasks.json is:

{
    "version": "0.1.0",
    "command": "dotnet",
    "isShellCommand": true,
    "args": [],
    "tasks": [
        {
            "taskName": "test",
            "args": [
                "${workspaceRoot}/xunitexample.csproj"
            ],
            "isBuildCommand": true,
            "problemMatcher": "$msCompile"
        }
    ]
}

It seems to run to completion with the output screen of:

But still it shows this configuration error message at the top of the status screen, in big glaring RED:

Error processing 'configurationDone' request. Unknown Error: 0x89720010

What is it and why it is being displayed?

Many thanks in advance.
