Extensions

We moved all namespaces into a single namespace. No matter which (WinUICommunity) library you use, the namespace is always as follows
For use in the Xaml:
xmlns:wuc="using:WinUICommunity"
For use in the Csharp:
using WinUICommunity;

ContentDialogExtension

By default, only 1 ContentDialog can be opened, with the help of this extension you can open multiple ContentDialogs.

ContentDialog dialog = new ContentDialog()
{
    Title = "Title",
    Content = "Content",
    PrimaryButtonText = "OK",
    CloseButtonText = "Cancel",
    DefaultButton = ContentDialogButton.Primary,
    XamlRoot = xamlRoot
};
var result = await dialog.ShowAsyncQueue();
