How to implement in-app purchases in a Windows Store App

Question

I was wondering how exactly in-app purchases are implemented in Windows Store Apps (meaning not Windows Phone), simply because I've looked online and at Microsoft's tutorials and I have found nothing that seems to avail me.

I used Unity to develop my game and then exported a Windows Store 8.1 file. Specifically, I have an event implemented in my Unity code that is linked to a method in the MainPage.xaml.cs file accessible in Visual Studio (I am running Express 2013 for Windows). The actual method is being executed, but when I request a product purchase in the method like so, I get an error:

    // This is assigned to the event that is called in Unity whenever the "Get Points" button is pressed.
    private async void PurchasePoints(object arg)
    {
        // Find the GameManager GameObject.
        UnityEngine.GameObject gameManager = UnityEngine.GameObject.FindGameObjectWithTag("GameManager");

        // Get the script attached to it.
        GameManager gameManagerScript = gameManager.GetComponent<GameManager>();

        // Get the license information for this app.
        Windows.ApplicationModel.Store.LicenseInformation licenseInformation = Windows.ApplicationModel.Store.CurrentAppSimulator.LicenseInformation;

        if (licenseInformation.ProductLicenses["SectorDefense_Points_250"].IsActive)
        {
            await Windows.ApplicationModel.Store.CurrentAppSimulator.RequestProductPurchaseAsync("SectorDefense_Points_250");

            gameManagerScript.playerScore += 250;
        }
    }

I'm just generally confused as to how one is supposed to implement that sort of functionality.

I've made sure to look into the WindowsStoreProxy.xml file and customize everything within it to suit the app's needs, although I've never really worked with XML before.

Any help is much appreciated!

Thanks in advance.
