Visual Studio Code – Simple NET6 C++/CLR library cannot be used from NET6 console application

I’m attempting to wrap some native C++ code in a C++/CLI (CLR) library (TestClrLibrary.NetCore) in order to use it from a NET6 application. Everything built fine, and I was able to reference my library from another project (NET6 application) in the same solution. However, when I run the application, I always get the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'TestClrLibrary.NetCore, Version=1.0.8252.18682, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.
File name: 'TestClrLibrary.NetCore, Version=1.0.8252.18682, Culture=neutral, PublicKeyToken=null'
   at TestConsole.NetCore.Program.Main(String[] args)

I’m using VS2022, and created both projects with default settings for NET6. The header/source for the library look like this:

// TestClrLibrary.NetCore.h
#pragma once

using namespace System;

namespace TestClrLibraryNetCore {
    public ref class TestClass
    {
    public:
        void Open(System::String^ authority);
    };
}

// TestClrLibrary.NetCore.cpp
#include "pch.h"

#include "TestClrLibrary.NetCore.h"

namespace TestClrLibraryNetCore {
    void TestClass::Open(System::String^ authority)
    {

    }
}

The NET6 console application:

// Program.cs
namespace TestConsole.NetCore
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var test = new TestClrLibraryNetCore.TestClass();
            test.Open("arg0");

            Console.WriteLine($"Created test object.");
        }
    }
}

The library doesn’t actually do anything at this point, and it has no references beyond what are created when Visual Studio creates the project. The library build settings definitely use the /clr:netcore switch, and TargetFramework for both projects is net6.0. Both are x64, so I know that matches (the usual cause of errors like these).

This does seem to be a .Net Core / NET6 issue, because I can recreate both library & console exe projects targeting .Net Framework 4.8 and run the resulting application with no issues.

Is there something I’m missing? What does it take to get the simplest imaginable C++/CLR library built for use in a NET6 application?
