Build cross platform desktop apps with .NET 6 and Blazor, ASP.NET Core (Razor Pages, MVC).
Electron.NET is a wrapper around a native Electron application with an embedded ASP.NET Core application. Via our Electron.NET IPC bridge we can invoke Electron APIs from .NET.
The CLI extensions hosts our toolset to build and start Electron.NET applications.
Well... there are lots of different approaches how to get a X-plat desktop app running. We thought it would be nice for .NET devs to use the ASP.NET Core environment and just embed it inside a pretty robust X-plat enviroment called Electron. Porting Electron to .NET is not a goal of this project, at least we don't have any clue how to do it. We just combine ASP.NET Core & Electron.
The current Electron.NET CLI builds Windows/macOS/Linux binaries. Our API uses .NET 6, so our minimum base OS is the same as .NET 6.
Also you should have installed:
Besides the chat on Gitter and the issues discussed here you can also use StackOverflow with the tag electron.net.
If you want to sponsor the further maintenance and development of this project see the donate section.
To activate and communicate with the "native" (sort of native...) Electron API include the ElectronNET.API NuGet package in your ASP.NET Core app.
PM> Install-Package ElectronNET.APIYou start Electron.NET up with an UseElectron WebHostBuilder-Extension and open the Electron Window:
using ElectronNET.API;
using ElectronNET.API.Entities;
var builder = WebApplication.CreateBuilder(args);
builder.WebHost.UseElectron(args);
// Is optional, but you can use the Electron.NET API-Classes directly with DI (relevant if you want more encoupled code)
builder.Services.AddElectron();
var app = builder.Build();
...
await app.StartAsync();
// Open the Electron-Window here
await Electron.WindowManager.CreateWindowAsync();
app.WaitForShutdown();You start Electron.NET up with an UseElectron WebHostBuilder-Extension.
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseElectron(args);
webBuilder.UseStartup<Startup>();
});Open the Electron Window in the Startup.cs file:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
//...
Electron.WindowManager.CreateWindowAsync();
}To start the application make sure you have installed the "ElectronNET.CLI" packages as global tool:
dotnet tool install ElectronNET.CLI -gAt the first time, you need an Electron.NET project initialization. Type the following command in your ASP.NET Core folder:
electronize init- Now a electronnet.manifest.json should appear in your ASP.NET Core project
- Now run the following:
electronize startOnly the first
electronize startis slow. The next will go on faster.
The file watcher is included with version 8.31.1 of Electron.NET. For example, a file change can trigger compilation, test execution, or deployment. The Electron.NET window will automatically refresh and new code changes will be visible more quickly. The following Electron.NET CLI command is required:
electronize start /watchOnly the first
electronize startis slow. The next will go on faster.
Start your Electron.NET application with the Electron.NET CLI command. In Visual Studio attach to your running application instance. Go in the Debug Menu and click on Attach to Process.... Sort by your projectname on the right and select it on the list.
A complete documentation will follow. Until then take a look in the source code of the sample application:
Electron.NET API Demos
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
Here you need the Electron.NET CLI as well. Type the following command in your ASP.NET Core folder:
electronize build /target winThere are additional platforms available:
electronize build /target win
electronize build /target osx
electronize build /target linuxThose three "default" targets will produce x64 packages for those platforms.
For certain NuGet packages or certain scenarios you may want to build a pure x86 application. To support those things you can define the desired .NET Core runtime, the electron platform and electron architecture like this:
electronize build /target custom "win7-x86;win32" /electron-arch ia32 The end result should be an electron app under your /bin/desktop folder.
macOS builds can't be created on Windows machines because they require symlinks that aren't supported on Windows (per this Electron issue). macOS builds can be produced on either Linux or macOS machines.
After an update to the latest Electron.API package, an update to the latest Electron.CLI is always required. In addition, always update the CLI via NuGet:

This video provides an introduction to development for Electron.NET: Electron.NET - Contributing Getting Started
This repository consists of the main parts (API & CLI) and it's own "playground" ASP.NET Core application. Both main parts produce local NuGet packages, that are versioned with 99.0.0. The first thing you will need is to run one of the build scripts (.cmd or .ps1 for Windows, the .sh for macOS/Linux).
If you look for pure demo projects checkout the other repositories.
The problem working with this repository is, that NuGet has a pretty aggressive cache, see here for further information.
We do this open source work in our free time. If you'd like us to invest more time on it, please donate. Donation can be used to increase some issue priority. Thank you!

Enjoy!
Make sure you also have the new Electron.NET API & CLI 9.31.2 version.
dotnet tool update ElectronNET.CLI -gThis now uses electron-builder and the necessary configuration to build is made in the electron.manifest.json file (on the build part). In addition, own Electron.NET configurations are stored (on the root).
Please make sure that your electron.manifest.json file has the following new structure:
{
"executable": "{{executable}}",
"splashscreen": {
"imageFile": ""
},
"name": "{{executable}}",
"author": "",
"singleInstance": false,
"build": {
"appId": "com.{{executable}}.app",
"productName": "{{executable}}",
"copyright": "Copyright © 2020",
"buildVersion": "1.0.0",
"compression": "maximum",
"directories": {
"output": "../../../bin/Desktop"
},
"extraResources": [
{
"from": "./bin",
"to": "bin",
"filter": ["**/*"]
}
],
"files": [
{
"from": "./ElectronHostHook/node_modules",
"to": "ElectronHostHook/node_modules",
"filter": ["**/*"]
},
"**/*"
]
}
}In the Version 0.0.9 the CLI was not a global tool and needed to be registered like this in the .csproj:
<ItemGroup>
<DotNetCliToolReference Include="ElectronNET.CLI" Version="0.0.9" />
</ItemGroup>After you edited the .csproj file, you need to restore your NuGet packages within your Project. Run the following command in your ASP.NET Core folder:
dotnet restoreIf you still use this version you will need to invoke it like this:
electronize ...Electron.NET requires Node.js integration to be enabled for IPC to function. If you are not using the IPC functionality you can disable Node.js integration like so:
WebPreferences wp = new WebPreferences();
wp.NodeIntegration = false;
BrowserWindowOptions browserWindowOptions = new BrowserWindowOptions
{
WebPreferences = wp
};ElectronNET.API can be added to your DI container within the Startup class. All of the modules available in Electron will be added as Singletons.
using ElectronNET.API;
public void ConfigureServices(IServiceCollection services)
{
services.AddElectron();
