unable to debug unit test

[mrj001]

Create a new solution:
$ dotnet new console -n MyConsole
$ dotnet new xunit -n test
$ dotnet add test/test.csproj reference MyConsole/MyConsole.csproj
$ dotnet sln program.sln add MyConsole/MyConsole.csproj
$ dotnet sln program.sln add test/test.csproj

Add this to Program.cs in MyConsole folder:

public static bool DoSomething()
{
return false;
}

Change Test1 to:

[Fact]
public void Test1()
{
Assert.True(Program.DoSomething());
}

$ dotnet build

succeeds
Launch vscode
Open the folder
Generate assets for build & debug
Select program to launch
Open the UnitTest1.cs file. Click “debug test”

I don't understand how this is a duplicate.

Issue #3459 is two years old. This was working for me up until a few weeks ago.
