The easiest way to get started is this:

![](https://raw.githubusercontent.com/AvaloniaCommunity/MessageBox.Avalonia/master/Images/standart-messagebox.png)

```cs
using MsBox.Avalonia;
using MsBox.Avalonia.Enums;

var box = MessageBoxManager
    .GetMessageBoxStandard("Caption", "Are you sure you would like to delete appender_replace_page_1?",
        ButtonEnum.YesNo);

var result = await box.ShowAsync();
```
You have a lot of options how to show your messagebox:

`ShowAsync` -   Show messagebox depending on the type of application

If application is SingleViewApplicationLifetime (Mobile or Browses) then show messagebox as popup
      
      If application is ClassicDesktopStyleApplicationLifetime (Desktop) then show messagebox as window

`ShowWindowAsync` - Show messagebox as window

`ShowWindowDialogAsync` - Show messagebox as window with owner

`ShowAsPopupAsync` - Show messagebox as popup

HyperLink with powerfull options:

```cs
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using Avalonia.Controls;
using MsBox.Avalonia;
using MsBox.Avalonia.Dto;
using MsBox.Avalonia.Models;

MessageBoxManager.GetMessageBoxCustom(
    new MessageBoxCustomParams
    {
        ButtonDefinitions = new List<ButtonDefinition>
        {
            new ButtonDefinition { Name = "Yes", },
            new ButtonDefinition { Name = "No", },
            new ButtonDefinition { Name = "Cancel", }
        },
        ContentTitle = "title",
        ContentMessage = "Informative note:" +
                         "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ut pulvinar est, eget porttitor magna. Maecenas nunc elit, pretium nec mauris vel, cursus faucibus leo. Mauris consequat magna vel mi malesuada semper. Donec nunc justo, rhoncus vel viverra a, ultrices vel nibh. Praesent ut libero a nunc placerat vulputate. Morbi ullamcorper pharetra lectus, ut lobortis ex consequat sit amet. Vestibulum pellentesque quam at justo hendrerit, et tincidunt nisl mattis. Curabitur eu nibh enim.\n",
        Icon = MsBox.Avalonia.Enums.Icon.Question,
        WindowStartupLocation = WindowStartupLocation.CenterOwner,
        CanResize = false,
        MaxWidth = 500,
        MaxHeight = 800,
        SizeToContent = SizeToContent.WidthAndHeight,
        ShowInCenter = true,
        Topmost = false,
        HyperLinkParams = new HyperLinkParams
        {
            Text = "https://docs.avaloniaui.net/",
            Action = new Action(() =>
            {
                var desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
                var url = "https://docs.avaloniaui.net/";
                if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
                {
                    //https://stackoverflow.com/a/2796367/241446
                    using var proc = new Process { StartInfo = { UseShellExecute = true, FileName = url } };
                    proc.Start();

return;
                }

if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
                {
                    Process.Start("x-www-browser", url);
                    return;
                }

if (!RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
                    throw new Exception("invalid url: " + url);
                Process.Start("open", url);
                return;
            })
        }
    });
```

**Important: Async/Await Usage**

Always use `await` when calling MessageBox methods. **Never** use `.Result` or `.Wait()` on the Task, as this will cause a deadlock and freeze your UI.

**❌ Wrong (will freeze your application):**
```cs
private void ShowMessage()
{
    var box = MessageBoxManager.GetMessageBoxStandard("Title", "Message", ButtonEnum.Ok);
    var result = box.ShowAsync().Result; // DON'T DO THIS!
}
```

**✅ Correct:**
```cs
private async void ShowMessage()
{
    var box = MessageBoxManager.GetMessageBoxStandard("Title", "Message", ButtonEnum.Ok);
    var result = await box.ShowAsync(); // Use await
}
```

If you need to return the result to the caller, make sure the entire call chain is async:
```cs
private async Task<ButtonResult> ShowConfirmation()
{
    var box = MessageBoxManager.GetMessageBoxStandard("Confirm", "Are you sure?", ButtonEnum.YesNo);
    return await box.ShowAsync();
}

// Usage:
var result = await ShowConfirmation();
if (result == ButtonResult.Yes)
{
    // Handle confirmation
}
```

**Markdown support**

Do enable markdown support users need to:

- install MessageBox.Avalonia.Markdown package

- add MarkdownView from :MsBox.Avalonia.Markdown to App.axaml
```
    <Application.Styles>
        <StyleInclude Source="avares://MsBox.Avalonia.Markdown/Controls/MarkdownView.axaml" />
    </Application.Styles>
```
