# AvaloniaCrossPlat
|
|
_Prerequisites: vpk command line tool installed_
|
|
|
|
This app demonstrates how to use Avalonia to provide a desktop UI, installer, and updates for Mac, Linux, and Windows.
|
|
|
|
You can run this sample by executing the build script with a version number (eg. `build-win.bat 1.0.0`).
|
|
There are build scripts provided for each platform (`build-win.bat`, `build-linux.sh`, `build-osx.bat`).
|
|
|
|
Once built, you can install the app - build more updates, and then test updates and so forth. The sample app will check the local release dir for new update packages.
|
|
|
|
In your production apps, you should deploy your updates to some kind of update server instead.
|
|
|
|
On Linux, there is no installer, since the program is shipped as a `.AppImage`, it is only portable - however it can still update itself by replacing it's own `.AppImage` (even if that `.AppImage` is inside priveleged directories)
|

|
## Avalonia Implementation Notes
|
|
The Avalonia Template will generate a `Program.Main()` for you. You need to be careful when editing this file as to not break the Avalonia designer. You must not delete the `BuildAvaloniaApp()` function, but you must add the `VelopackApp` builder to the `Main()` method. For example:
|
|
|
|
```cs
|
|
class Program
|
|
{
|
|
// Initialization code. Don't use any Avalonia, third-party APIs or any
|
|
// SynchronizationContext-reliant code before AppMain is called.
|
|
// things aren't initialized yet and stuff might break.
|
|
[STAThread]
|
|
public static void Main(string[] args)
|
|
{
|
|
VelopackApp.Build().Run();
|
|
BuildAvaloniaApp().StartWithClassicDesktopLifetime(args);
|
|
}
|
|
|
|
// Avalonia configuration, don't remove method; also used by visual designer.
|
|
public static AppBuilder BuildAvaloniaApp()
|
|
{
|
|
return AppBuilder.Configure<App>()
|
|
.UsePlatformDetect()
|
|
.WithInterFont()
|
|
.LogToTrace();
|
|
}
|
|
}
|
|
``` |
