Passing Objects between different Razor Pages in Blazor

Question

I'm new to blazor and working on an adress Manager. Here I have a .razor page, where the user can create a new contact.

Now, to add the contact to the list of contacts (in my MainLayout.razor file), I eather need to pass the new contact to the MainLayout.razor file, or the list of contacts to my other .razor page. Any Ideas or suggestions on how i can pass objects between .razor pages?

Here is my code:

My MainLayout, which has the Manager Controller Object, which has the contact list i need to acces.

@inherits LayoutComponentBase
@inject NavigationManager NavigationManager
@using BlazorAdressManager.Shared.Controller
@using BlazorAdressManager.Shared.Model







    

        
            
            
                
                    9 Kontakte
                    

                        @foreach (var contact in contactList){
                            
                                
                                    
                                
                                @contact.getName()
                                @contact.getMail()
                                
                                    delete
                                
                            
                        }
                    
                
                
                    @Body
                
            
        

        


@code {
    private ManagerController mc;
    private Manager manager;
    private ContactController cc;
    private List contactList;

    private void Navigate(string path)
    {
        NavigationManager.NavigateTo(path);  
    }   

    protected override void OnInitialized()
    {
        mc = new ManagerController();
        manager = mc.getManager();
        cc = mc.getContactController();
        contactList = manager.getContactList();

        Contact dummy = new Contact();
        dummy.setName("dummy");
        dummy.setMail("ichbbineindummy@geil.org");
        cc.addContact(dummy);
    }
}

And here is my AddView.Razor file: Here, i create a new contact. So I eather need this specific contact object in my MainLayout.razor file, or the Specific ManagerController object in my AddView.razor file.

@page "/add-view"
@inject NavigationManager NavigationManager
@using BlazorAdressManager.Shared.Controller
@using BlazorAdressManager.Shared.Model
