Blazor linker strips away a method in a generated class even if the settings indicate not to.

Environment:
* Windows 10 Enterprise
* Version 10.0.19043 Build 19043
* Visual Studio 2022 Current
* .NET 6.0

Steps to reproduce the issue:
* clone the repository at https://github.com/kephas-software/kephas (master)
* open the src/Kephas.sln solution and build it.
* start the Blazor app in Tests/Kephas.AspNetCore.Blazor.InteractiveTests/Kephas.AspNetCore.Blazor.InteractiveTests.Server
* the application crashes while bootstrapping, the stack trace is visible in the browser console (see the attachment).

Due to the fact that it happens during bootstrap I cannot debug properly, but I managed to trace down to the code causing the issue:
\src\Kephas.Injection\Services\AppServicesAttribute.cs, line 131.
When the returned instance is returned to the caller, either the ToArray() extension method or the SelectMany() crashes.

Background:
* the AppServicesAttribute is used to collect services for the dependency injection through a provider class, provided in the constructor and implementing the IAppServiceInfosProvider interface.
* This attribute implements itself the IAppServiceInfosProvider interface, redirecting the interface methods to the instance created upon request.
* The provider type is annotated with ```[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.All)]``` in the AppServicesAttribute's constructor.
* The provider classes are generated by an analyzer, one per assembly. The generated class where the issue occurs is listed below (can be found, after compilation, in src/Kephas.Application/obj/.generated/Kephas.Analyzers/Kephas.Analyzers.Injection.AppServicesSourceGenerator/AppServices.g.cs

``` C#
#nullable enable

using System;
using System.Collections.Generic;
using System.Diagnostics.CodeAnalysis;

using Kephas.Services;

[assembly: AppServices(typeof(Kephas.Injection.Generated.AppServices_Kephas_Application))]

namespace Kephas.Injection.Generated
{
#if NET6_0_OR_GREATER
[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.All)]
#endif
internal partial class AppServices_Kephas_Application: IAppServiceInfosProvider
{
IEnumerable? IAppServiceInfosProvider.GetContractDeclarationTypes(IContext? context)
{
yield return typeof(Kephas.Application.IAppMainLoop);
yield return typeof(Kephas.Application.IAppManager);
yield return typeof(Kephas.Application.IFeatureLifecycleBehavior);
yield return typeof(Kephas.Application.IFeatureManager);
}

IEnumerable IAppServiceInfosProvider.GetAppServices(IContext? context)
{
yield return new ServiceDeclaration(typeof(Kephas.Application.CommandsAppSetupHandler), typeof(Kephas.Application.IAppSetupHandler));
yield return new ServiceDeclaration(typeof(Kephas.Application.DefaultAppMainLoop), typeof(Kephas.Application.IAppMainLoop));
yield return new ServiceDeclaration(typeof(Kephas.Application.DefaultAppManager), typeof(Kephas.Application.IAppManager));
yield return new ServiceDeclaration(typeof(Kephas.Application.FeatureEnabledServiceBehavior), typeof(Kephas.Services.Behaviors.IEnabledServiceBehaviorRule<, >));
yield return new ServiceDeclaration(typeof(Kephas.Application.Interaction.InteractionFeatureLifecycleBehavior), typeof(Kephas.Application.IFeatureLifecycleBehavior));
yield return new ServiceDeclaration(typeof(Kephas.Application.MainLoopAppLifecycleBehavior), typeof(Kephas.Application.IAppLifecycleBehavior));
yield return new ServiceDeclaration(typeof(Kephas.Application.SetupAppLifecycleBehavior), typeof(Kephas.Application.IAppLifecycleBehavior));
yield return new ServiceDeclaration(typeof(Kephas.Application.StartupAppLifecycleBehavior), typeof(Kephas.Application.IAppLifecycleBehavior));
}
}
}

```

From intermediary steps, which I cannot reproduce anymore, I am quite certain that the method ```IAppServiceInfosProvider.GetAppServices``` is called for ```AppServices_Kephas_Application```. However, presumably, the object returned is missing some methods leading to the error in ```class-setup-vtable.c```. I tried to indicate at all steps that the assemblies should not be trimmed, due to heavy use of reflection, but to no avail.
