I have two projects:
“TestA” project config:

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

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
      <GenerateAssemblyInfo>true</GenerateAssemblyInfo>
  </PropertyGroup>
    <ItemGroup>
        <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
            <_Parameter1>$(MSBuildProjectName).Abca</_Parameter1>
        </AssemblyAttribute>
        <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
            <_Parameter1>$(AssemblyName).Abca</_Parameter1>
        </AssemblyAttribute>
    </ItemGroup>
</Project>

and code is:

namespace TestA
{
    internal class MyClass
    {
        public void Hello()
        {
           
        }
    }
}.

“TestB” project config:
Test.Abca

namespace Test.Abca
{
    using TestA;
    internal class Class1
    {
        internal void Foo()
        {
             MyClass myClass =new MyClass();//'MyClass' is inaccessible due to its protection level
          
        }
    }
}

I added the TestA reference to Test.Abca but got an error when using the code:
error CS0122: ‘MyClass’ is inaccessible due to its protection level

I tried improving the InternalsVisibleTo setting to various types but it didn’t work, it only worked when sure with the name “Test.Abca”. This is something I do not want.
What I want is to be used for many projects named like “Test.***”.
