Blazor Wasm Static Content Error
When I load a static html file, I get this error in the console Failed to load resource: net::ERR_CONTENT_DECODING_FAILED The actual network request gives a Ok (200) When i check the file in sources, i get the message Content unavailable. Resource was not cached Im trying to load it in an iframe, but the same thing happens if I load the file in the browser. When I request with postman, the request works perfectly fine.

WinUI: Creating a DataTemplate through Code doesent resolve all bindings.
I have a binding attachment that lets me add items to a MenuBarItem dynamically. It adds an ItemSource and ItemTemplate. 
<MenuFlyoutSubItem Text="{Binding Name}" ctrl:BindableMenuBarItem.ItemsSource="{Binding Operations}" ctrl:PrintAttachment.Print="{Binding Operations}">
    <ctrl:BindableMenuBarItem.ItemTemplate>
        <DataTemplate>
            <MenuFlyoutItem Text="{Binding Name}" CommandParameter="{Binding}" Command="{Binding AddOperationCommand,ElementName=vm}"/>
        </DataTemplate>
    </ctrl:BindableMenuBarItem.ItemTemplate>
</MenuFlyoutSubItem>
<MenuFlyoutSubItem Text="{Binding Name}" ctrl:BindableMenuBarItem.ItemsSource="{Binding Operations}" ctrl:PrintAttachment.Print="{Binding Operations}">
    <ctrl:BindableMenuBarItem.ItemTemplate>
        <DataTemplate>
            <MenuFlyoutItem Text="{Binding Name}" CommandParameter="{Binding}" Command="{Binding AddOperationCommand,ElementName=vm}"/>
        </DataTemplate>
    </ctrl:BindableMenuBarItem.ItemTemplate>
</MenuFlyoutSubItem>
The Name and CommandParameter bindings both get set, but the command binding doesent run at all, presumably due to the ElementName. I even created a special print attachment property and if I had ElementName, it didnt print anything, but it did correctly print the other things. This might be because i have to create the DataTemplates in the code behind that it doesent let things with relative bindings get set. This is what I do. 
    static async void BuildArguments(MenuFlyoutSubItem m, IEnumerable source, DataTemplate template)
    {
        try
        {
            Action h = () =>
            {
                m.Items.Clear();
                foreach (var item in source)
                {
                    var content = (MenuFlyoutItemBase)template.LoadContent();
                    content.DataContext = item;
                    m.Items.Add(content);
                }
            };
            await m.DispatcherQueue.EnqueueAsync(h, DispatcherQueuePriority.Normal);
        }
        catch (Exception ex)
        {
            Debug.WriteLine($"error creating menu bar sub items: '{ex.Message}'");
        }
    }
    static async void BuildArguments(MenuFlyoutSubItem m, IEnumerable source, DataTemplate template)
    {
        try
        {
            Action h = () =>
            {
                m.Items.Clear();
                foreach (var item in source)
                {
                    var content = (MenuFlyoutItemBase)template.LoadContent();
                    content.DataContext = item;
                    m.Items.Add(content);
                }
            };
            await m.DispatcherQueue.EnqueueAsync(h, DispatcherQueuePriority.Normal);
        }
        catch (Exception ex)
        {
            Debug.WriteLine($"error creating menu bar sub items: '{ex.Message}'");
        }
    }
Is my problem the way I create the child contents, and if so what can I do to fix it.

❔ Fire and forget
Is there a recommended way to call an async void, or to run an async task as fire and forget? I havent been able to find any that doesent cause a warning, and i would rather not supress it.
