ElectronNET.Core.API 0.2.0-pre.239

Electron.NET Core is here!

A Complete Transformation

ElectronNET.Core represents a fundamental modernization of Electron.NET, addressing years of accumulated pain points while preserving full API compatibility. This isn't just an update — it's a complete rethinking of how .NET developers build and debug cross-platform desktop applications with Electron.

Build cross platform desktop applications with .NET 6/8/10 - from console apps to ASP.NET Core (Razor Pages, MVC) to Blazor.

Wait - how does that work exactly?

Well... there are lots of different approaches how to get a X-plat desktop app running. Electron.NET provides a range of ways to build .NET based solutions using Electron at the side of presentation.

While the classic Electron.NET setup, using an ASP.NET host ran by the Electron side is still the primary way, there's more flexibility now: both, dotnet and Electron are now able to launch the other for better lifetime management, and when you don't need a local web server - like when running content from files or remote servers, you can drop the ASP.NET stack altogether and got with a lightweight console app instead.

📦 NuGet

• ElectronNET.Core:
• ElectronNET.Core.API:
• ElectronNET.Core.AspNet:

🛠 Requirements to Run

You should have installed:

• .NET 6/8 or later.
• The minimum base OS is the same as .NET 6 / .NET 8.
• Node.JS using at least Version 22.x.

👩‍🏫 Usage with ASP.NET

• Create a new ASP.NET Core project
• Install the following two NuGet packages:

dotnet add package ElectronNET.Core

dotnet add package ElectronNET.Core.AspNet

Classic ASP.NET Core

Enable Electron.NET on Startup

To do so, use the UseElectron extension method on a WebApplicationBuilder, an IWebHostBuilder or any descendants.

Program.cs

using ElectronNET.API;
using ElectronNET.API.Entities;

public static void Main(string[] args)
{
    WebHost.CreateDefaultBuilder(args)
        .UseElectron(args, ElectronAppReady)
        .UseStartup<Startup>()
        .Build()
        .Run();
}

public static async Task ElectronAppReady()
{
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(
        new BrowserWindowOptions { Show = false });

    browserWindow.OnReadyToShow += () => browserWindow.Show();
}

Minimal API Example

For a minimal API you can use:

using ElectronNET;
using ElectronNET.API;
using ElectronNET.API.Entities;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddRazorPages();
builder.Services.AddElectron(); // <- might be useful to set up DI

builder.UseElectron(args, async () =>
{
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(
        new BrowserWindowOptions { Show = false, AutoHideMenuBar = true });

    browserWindow.OnReadyToShow += () => browserWindow.Show();
});

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
}

app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.MapRazorPages();
app.Run();

Blazor

For a project with Blazor you can use:

using ElectronNET.API;
using ElectronNET.API.Entities;

var builder = WebApplication.CreateBuilder(args);

builder.Services
    .AddRazorComponents()
    .AddInteractiveWebAssemblyComponents();

builder.Services.AddElectron(); // <-- might be useful to set up DI

builder.UseElectron(args, async () =>
{
    var options = new BrowserWindowOptions {
        Show = false,
        AutoHideMenuBar = true,
        IsRunningBlazor = true, // <-- crucial
    };
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(options);
    browserWindow.OnReadyToShow += () => browserWindow.Show();
});

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseWebAssemblyDebugging();
}
else
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
}

app.UseStaticFiles();
app.UseAntiforgery();

app.MapRazorComponents<BlazorApp.Components.App>()
    .AddInteractiveWebAssemblyRenderMode();

app.Run();

The IsRunningBlazor option makes sure to set up the renderer in a way that Blazor can just run without any interference. This includes things such as HMR for development.

🚀 Starting and Debugging the Application

Just press F5 in Visual Studio or use dotnet for debugging.

📔 Usage of the Electron API

A complete documentation is available on the Wiki.

In this YouTube video, we show you how you can create a new project, use the Electron.NET API, debug a application and build an executable desktop app for Windows: Electron.NET - Getting Started
