The easy/stupid way.

I have two versions of NavMenu I want to display.

User is not logged in
User is logged in.

In NavMenu, I have a switch:

Partial code from NavMenu:

<div class="@NavMenuCssClass nav-scrollable">
    <nav class="flex-column">
        @if (UserName == "")
        {//not logged in 
            <div class="nav-item px-3">
                <NavLink class="nav-link" href="Register">
                    <span class="oi oi-list-rich" aria-hidden="true"></span> Register
                </NavLink>
            </div>
        }
        else
        {//logged in

First visit UserName is a zero length string.

Now in the login page I put: (I know it is stupid, but it works)

This is AFTER the User has successfully entered UserName/Password:

            if (success)
            {
                // This FORCES NavMenu.OnInitializedAsync() to run again.
                // Passing a value in the QueryString allows NavMenu to reload with whatever
                NavigationManager.NavigateTo("MyProject.Shared.NavMenu/LoggedIn", false, true);
            }

So I call NavMenu DIRECTLY with NavigationManager, passing "LoggedIn" on the command line.

This forces NavMenu OnInitialized to run again and give a little info.

Back in NavMenu @code:

        var uri = NavigationManager.ToAbsoluteUri(NavigationManager.Uri);

        // If NavMenu is called directly, then I wanted it to reload.
        // If the path was "LoggedIn" just go to Index
        // The first time through (not logged in) UserName is blank!!
        if (uri.AbsolutePath == "/TADEXT.Shared.NavMenu/LoggedIn")
        {
            NavigationManager.NavigateTo("/", false, true);
        }

Sometime stupid things work great.
