EZ_Updater

EZ_Updater is an updater for standalone .NET apps that relies on GitHub releases.
Supports exe and zip files (which can contain multiple files).

NuGet Package Install

PM> Install-Package EZ_Updater

Supported .NET versions

• .NET Framework 4.7.1 or above
• .NET Core 3.1
• .NET 5.0 or above

How it works

EZ_Updater checks latest GitHub release on the repository specified, it returns a bool if the tag version is higher than your program File Version returns true else false. You can download the asset that matches your programname.exe. In case you want to download other file like a zip, you should specify it.

Current version detection

EZ_Updater uses File version to determine the current version of the application. You can update it by going to Properties of the project.

GitHub release version

GitHub tag can follow this format (Major).(Minor).(Patch).(Build) It´s not obligatory to use Minor, Patch and Build. There could be any letter or word on the tag name. Examples:

• Tag name: 1.0
• Tag name: v1.0.0
• Tag name: v1.0.0.0-beta

Usage example for GUI on WinForms and WPF

It can be used in console as well

 

WinForms

Add a reference to

using EZ_Updater;

Now on your form load you could do something like

private async void Form_Loaded(object sender, EventArgs e)
{
    Updater.GitHub_User = "Your GitHub User Name";
    Updater.GitHub_Repository = "Your GitHub Repository";
    Updater.OriginalFileName = "Your .exe (or whatever) file name";

    if (await Updater.CheckUpdateAsync() && MessageBox.Show("Update available\nDo you want to update?", "Confirmation", MessageBoxButtons.YesNo) == DialogResult.Yes)
    {
        if(Updater.CannotWriteOnDir)
            MessageBox.Show("Application cannot update in current directory, consider moving it to another folder or executing with Admin rights", "Alert");
        else
        {
            new UpdateForm()
            {
                Owner = this
            }.ShowDialog();
        }
    }
}

To force the update don't use the MessageBox There also exist a synchronous CheckUpdate if you are interested in

Update Form (WinForms)

Add a reference to

using EZ_Updater;

I recommend having a Button hidden for UpdateForm closing and a ProgressBar

In your form constructor you could do something like

Closebutton.Visible = false;
Updater.Update(UIChange);

If you want to download other asset rather than yourprogram.exe then you should

Closebutton.Visible = false;
Updater.GitHub_Asset = "YourAsset.zip";
Updater.Update(UIChange);

For the method sent in Updater.Update is recommended to be like this

private void UIChange(object sender, EventArgs e)
{
    Messagelabel.Text = Updater.Message;
    progressBar.Value = Updater.ProgressPercentage;

    switch (Updater.ShortState)
    {
        case UpdaterShortState.Canceled:
            Closebutton.Visible = true;
            break;
        case UpdaterShortState.Installed:
            Application.Restart();
            break;
    }
}

WPF

Add a reference to

using EZ_Updater;

Now on your window load you could do something like

private async void Window_Loaded(object sender, RoutedEventArgs e)
{
    Updater.GitHub_User = "Your GitHub User Name";
    Updater.GitHub_Repository = "Your GitHub Repository";
    Updater.OriginalFileName = "Your .exe (or whatever) file name";

    if (await Updater.CheckUpdateAsync() && MessageBox.Show("Update available\nDo you want to update?", "Confirmation", MessageBoxButton.YesNoCancel) == MessageBoxResult.Yes)
    {
        if(Updater.CannotWriteOnDir)
            MessageBox.Show("Application cannot update in current directory, consider moving it to another folder or executing with Admin rights", "Alert");
        else
        {
            new UpdateForm()
            {
                Owner = this
            }.ShowDialog();
        }
    }
}

To force the update don't use the MessageBox There also exist a synchronous CheckUpdate if you are interested in

Update Window (WPF)

Add a reference to

using EZ_Updater;

I recommend having a Button hidden for UpdateForm closing and a ProgressBar

In your form constructor you could do something like

Closebutton.Visibility = Visibility.Hidden;
Updater.Update(UIChange);

If you want to download other asset rather than yourprogram.exe then you should

Closebutton.Visibility = Visibility.Hidden;
Updater.GitHub_Asset = "YourAsset.zip";
Updater.Update(UIChange);

For the method sent in Updater.Update is recommended to be like this

private void UIChange(object sender, EventArgs e)
{
    Messagelabel.Content = Updater.Message;
    progressBar.Value = Updater.ProgressPercentage;

    switch (Updater.ShortState)
    {
        case UpdaterShortState.Canceled:
            Closebutton.Visibility = Visibility.Visible;
            break;
        case UpdaterShortState.Installed:
            Process.Start(Updater.ProgramFileName);
            Application.Current.Shutdown();
            break;
    }
}
