Global Variable to Store the Await Statement in C#

Issue

I have an await statement await SecureStorage.GetAsync("RegisteredUserID");, which stored the User Id, in the Xamarin Secure Storage. The SetAsynch and GetAsynch can be only used with await in Asynch Function.

But, In my App, in App.xml.cs file, there is an Synchronize Function, where I want to get the value from Secure Storage and use as the value for options.AgentName.

It seems like the Global Variable is one of the Solution. How could I achieve this?

public static IHostBuilder BuildHost(Assembly platformSpecific = null) =>
            XamarinHost.CreateDefaultBuilder<App>()
                .ConfigureServices((_, services) =>
                {
                    services.AddAriesFramework(builder => builder.RegisterEdgeAgent(
                        options: options =>
                        {
                            options.AgentName = "Mobile Holder";

                            // Code
                });

UPDATE

public string UserId { get; private set; }

protected override async void OnStart()
{
    UserId = await SecureStorage.GetAsync("RegisteredPIN");
}

Solution

create a public property in App and set it's value in OnStart

public string UserId { get; private set; }

protected override async void OnStart()
{
    UserId = await SecureStorage.GetAsync("RegisteredPIN");
}

then anywhere in your app you can access the value

((App)App.Current).UserId
