Error Description: I'm trying to learn ApplicationPart(https://docs.microsoft.com/zh-cn/aspnet/core/mvc/advanced/app-parts?view=aspnetcore-5.0) , and when i load the applicationpart class library with assembly

        var mvcBuilder = services.AddMvc();

        var assemblies = AssemblyHelper.GetAssemblies(AppSetting.ModuleDir);
        foreach (var assembly in assemblies)
        {
            if (AppSetting.LoadModules == null || !AppSetting.LoadModules.Contains<string>(assembly.GetName().Name))
            {
                continue;
            }
            mvcBuilder.SetCompatibilityVersion(CompatibilityVersion.Version_3_0).AddApplicationPart(assembly);
        }
