We recently lifted .NET Framework project to .NET 7. All went without major complications, but we encountered an issue when we were trying to execute test cases from a .NET 7 test library using NUnit Console 3.16.3 (Release). The interesting fact is that the tests are running fine when ran from Visual Studio, but as longs as we run them from the console runner the following error is encountered.
1) Error : TestRunnerModule.Integration.Tests.ConnectionTestRunnerIntegrationTests.TestRunnerPortTestUpdate_UpdatesWizardData(READyCollector)
Autofac.Core.Registration.ComponentNotRegisteredException : The requested service 'MediatorModule.IMediator' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.
See https://autofac.rtfd.io/help/service-not-registered for more info.

In the test case we use IoC (Autofac 7.0.1) and we are loading assembly modules using Module Scanning. Module scanning is performed with the RegisterAssemblyModules() registration method, which does exactly what its name suggests.
var path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
List<Assembly> allAssemblies = new List<Assembly>();
foreach (string dll in Directory.GetFiles(path, "*MediatorModule.dll"))
{
allAssemblies.Add(Assembly.LoadFrom(dll));
}
foreach (string dll in Directory.GetFiles(path, "*WizardDataModule.dll"))
{
allAssemblies.Add(Assembly.LoadFrom(dll));
}
allAssemblies.Add(Assembly.GetExecutingAssembly());
var builder = new ContainerBuilder();
builder.RegisterAssemblyModules(allAssemblies.ToArray());
Container = builder.Build();
When trying to resolve registered assembly / ies (see below) the exception mentioned in the beginning is thrown.
using (var scope = Container.BeginLifetimeScope())
{
var mediator = scope.Resolve<IMediator>();
var wizardDataModule = scope.Resolve<IWizardDataModule>();
...
I am not sure this is the correct place to report this, but the whole thing works fine in the Visual Studio environment, but not through the NUnit Console 3.16.3 (Release).
