Calling async methods in Blazor view

Question

I have a server-side blazor client and I'm trying to modify the MainLayout razor page by having a Login check. I'm currently using Blazored for localstorage saving, and I'm currently using to see if a token is saved to see if user is logged in, however I'm not sure how I translate this in the if statement in razor page because it wants async method.

My login check is pretty simple as shown below.

public async Task<bool> IsLoggedIn()
{
    return await m_localStorage.ContainKeyAsync("token").ConfigureAwait(false);
}

In my Razor page I'm doing this statement check - which obvious doesn't work as there's no async modifier

@if (!await AppState.IsLoggedIn()) //Requires async modifier
{
    <a href="Login" target="_blank">Login</a>
}

I've also tried doing it using the .Result property, but this results in an exception thrown: (System.AggregateException: 'Information: Executed an implicit handler method, returned result Microsoft.AspNetC)' with an inner-exception -> NullReferenceException: Object reference not set to an instance of an object.

But from what I can see AppState is injected correctly and the local storage seems to be injected correctly in AppState.

@if (!AppState.IsLoggedIn().Result)
{
    <a href="Login" target="_blank">Login</a>
}

So my question is what is the correct way to approach this, is there a way to execute async methods in razor pages?
