⭐ About

NanUI is an open source framework on .NET platform for creating user interface for WinForm Applications using HTML5, CSS3, and JavaScript. It is based on the Xilium.CefGlue project, which is a .NET wrapper around the Chromium Embedded Framework.

If you are looking for a framework for creating a WinForm application with a modern user interface, NanUI is a good choice. you can use HTML, CSS, and JavaScript to create a user interface, and use C# to write the business logic of the application.

Please give NanUI project a star⭐ if you like it.

If this project helps, please consider funding it.

✨ Recommended for developers interested in WebView2

If you think that NanUI based on CEF is too heavy, you can try the WinFormedge project now. It is a lightweight WinForm framework based on WebView2 as the core. Suitable for developers who do not want to integrate libcef, using WinFormege and cooperating with the WebView2 that comes with the Windows system will effectively reduce the size of the application release package.

After testing, the size of the .NET 8.0 x64 + WinFormedge application packaged with ZIP compression is only 36MB, while the application packaged with NanUI is at least 125M after compression.

But it should be noted that applications created with WinFormedge can only run on Windows 10 and Windows 11, while NanUI supports Windows 7 SP1 and above.

🖥️ Requirements

For Development

• .NET Framework 4.6.2 or higher / .NET 6.0 or higher
• Visual Studio 2019 or higher (VS2022 is recommended)

For Deployment

• Microsoft Windows 7 Service Pack 1 or higher
• .Net Framework 4.6.2 or higher
• .NET 6.0 for Windows 7 and higher.
• .NET 7.0/8.0 for Windows 10 and higher.

This is a Windows Only framework, it can not run on Linux or Mac OS.

The minimum supported Windows is Windows 7 Service Pack 1, and some features (such as DirectComposition Offscreen Rendering) are not supported on Windows 7.

🧰 Getting Started

Create a simple NanUI Application by following the steps below:

1. Create a WinForm Application by default template.

2. Install NanUI NuGet Package

Open the NuGet Package Manager to install or use NuGet Package Manager Console, and run the following command to install NanUI nuget package:

PM> Install-Package NetDimension.NanUI

Install the dependencies of Chromium Embedded Framework that NanUI depends on:

PM> Install-Package NetDimension.NanUI.Runtime

3. A basic NanUI application requires the following code:

Modify the code in the Program.cs file as follows:

using WinFormium;

class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        var builder = NanUIApp.CreateBuilder();

        builder.UseNanUIApp<MyApp>();

        var app = builder.Build();

        app.Run();
    }
}

Create a class implements NanUIAppStartup for configuring the application:

using NetDimension.NanUI;

class MyAPP : NanUIAppStartup
{
    protected override MainWindowCreationAction? UseMainWindow(MainWindowOptions opts)
    {
        // Configure the main window of this application
        return opts.UseMainFormium<MyWindow>();
    }

    protected override void ProgramMain(string[] args)
    {
        // The codes in Main function should be here, this function only runs in Main process. So it can prevent the codes in Main process running in sub-processes.
        ApplicationConfiguration.Initialize();
    }

    protected override void ConfigurationChromiumEmbedded(ChromiumEnvironmentBuiler cef)
    {
        // Configure the Chromium Embedded Framework here
    }

    protected override void ConfigureServices(IServiceCollection services)
    {
        // Configure the services of this application here
    }
}

Create a class implements Formium for configuring the main window of the application:

using NetDimension.NanUI;
using NetDimension.NanUI.Forms;

class MyWindow : Formium
{
    public MyWindow()
    {
        Url = "https://www.google.com";
    }

    protected override FormStyle ConfigureWindowStyle(WindowStyleBuilder builder)
    {
        // Configure the style of the window here or leave it blank to use the default style

        var style = builder.UseSystemForm();

        style.TitleBar = false;

        style.DefaultAppTitle = "My first WinFomrim app";

        return style;
    }
}

4. Build and run your NanUI application
