Flowing scope can't resolve IEnumerable<T>, where resolving T[] works

[dotnetjunkie]

• Simple Injector latest version
• Configured using ScopedLifestyle.Flowing
• Transient services registered as collection
• Those transient services have scoped dependencies

In this context, when the collection is resolved from the Scope it fails when resolved as IEnumerable<T> but succeeds when resolved as T[].

Exception message:

ServiceX is registered using the 'Scoped' lifestyle, but the instance is requested outside the context of an active (Scoped) scope. Please see https://simpleinjector.org/scoped for more information about how apply lifestyles and manage scopes.'

Unable to reproduce this issue. I created the following tests, but they both pass:

[TestMethod]
public void X()
{
    // Arrange
    var container = new Container();
    container.Options.DefaultScopedLifestyle = ScopedLifestyle.Flowing;

    container.Collection.Append<IPlugin, PluginImpl>(Lifestyle.Transient);
    container.Collection.Append<IPlugin, PluginImpl2>(Lifestyle.Transient);
    container.Collection.Append<IPlugin, PluginWithDependency<ILogger>>(Lifestyle.Transient);

    container.Register<ILogger, NullLogger>(Lifestyle.Scoped);

    using var scope = new Scope(container);

    // Act
    IEnumerable<IPlugin> loggersStream = scope.GetAllInstances<IPlugin>();

    var plugin1 = (PluginWithDependency<ILogger>)loggersStream.Last();
    var plugin2 = (PluginWithDependency<ILogger>)loggersStream.Last();

    // Assert
    Assert.AreNotSame(plugin1, plugin2);
    Assert.AreSame(plugin1.Dependency, plugin2.Dependency);
}

[TestMethod]
public void Y()
{
    // Arrange
    var container = new Container();
    container.Options.DefaultScopedLifestyle = ScopedLifestyle.Flowing;

    container.Collection.Append<IPlugin, PluginImpl>(Lifestyle.Transient);
    container.Collection.Append<IPlugin, PluginImpl2>(Lifestyle.Transient);
    container.Collection.Append<IPlugin, PluginWithDependency<ILogger>>(Lifestyle.Transient);

    container.Register<ILogger, NullLogger>(Lifestyle.Scoped);

    using var scope = new Scope(container);

    // Act
    IPlugin[] loggers1 = scope.GetInstance<IPlugin[]>();
    IPlugin[] loggers2 = scope.GetInstance<IPlugin[]>();

    var plugin1 = (PluginWithDependency<ILogger>)loggers1.Last();
    var plugin2 = (PluginWithDependency<ILogger>)loggers2.Last();

    // Assert
    Assert.AreNotSame(plugin1, plugin2);
    Assert.AreSame(plugin1.Dependency, plugin2.Dependency);
}
