A modern and cross-platform native window framework for .NET that lets you build desktop applications using web technologies — load any URL, render HTML strings, or embed a full Blazor application inside a native window

Supports Windows (WebView2), Linux (WebKit2GTK), and macOS (WKWebView)

Note: This project is a modern rework of Photino.Net, Photino.Net.Server, Photino.Blazor and Photino.Native and is not affiliated with or endorsed by the original Photino authors

Packages

Package	Description
	Core window builder and runtime
	Shared interfaces, types, enums, and delegates
	Pre-built Blazor components for custom window chrome
	Full Blazor app integration inside a native window
	ASP.NET Core web app running inside a native window
	JavaScript and Blazor interop utilities

Quick Start

Load a URL in a native window

Install: dotnet add package InfiniLore.InfiniFrame

using InfiniFrame;

var window = InfiniFrameWindowBuilder.Create()
    .SetTitle("My App")
    .SetSize(1280, 720)
    .Center()
    .SetStartUrl("https://example.com")
    .Build();

window.WaitForClose();

Embed a Blazor application

Install: dotnet add package InfiniLore.InfiniFrame.BlazorWebView

using InfiniFrame.BlazorWebView;

var builder = InfiniFrameBlazorAppBuilder.CreateDefault(args, w => w
    .SetTitle("My Blazor App")
    .SetSize(1280, 720)
    .Center()
);

builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Build().Run();

Host an ASP.NET Core web app

Install: dotnet add package InfiniLore.InfiniFrame.WebServer

using InfiniFrame.WebServer;

var app = InfiniFrameWebApplication.CreateBuilder(args)
    .Build()
    .UseAutoServerClose();

app.Run();

Architecture

Your Application
│
├── InfiniLore.InfiniFrame                ← Core: window builder & runtime
├── InfiniLore.InfiniFrame.BlazorWebView  ← Blazor app lifecycle
├── InfiniLore.InfiniFrame.WebServer      ← ASP.NET Core integration
│
├── InfiniLore.InfiniFrame.Blazor         ← Window chrome Razor components
├── InfiniLore.InfiniFrame.Js             ← JS/Blazor interop
│
└── InfiniLore.InfiniFrame.Shared         ← Interfaces, types, native interop
        └── InfiniFrame.Native (internal) ← C++ platform layer

Only one of BlazorWebView, WebServer, or the core InfiniFrame package is needed for a given application type — they are independent integration paths

Examples

Example	What it demonstrates
BlazorWebView	Basic Blazor app in a native window
BlazorWebView.MultiWindowSample	Multiple independent windows with different Blazor components
WebApp.Blazor	Blazor Server hosted via ASP.NET Core
WebApp.React	React frontend with custom scheme handler and web messaging
WebApp.Vue	Vue.js frontend with all built-in JS message handlers

Repo history

This repo was originally forked from Photino.NET and then the history of the Photino.Blazor and Photino.Net.Server repositories were merged into this. By merging the histories, it was possible to ease further development, especially whilst also preserving the original commit history and attribution from the contributors of Photino.

This was also done for the Photino.Native library, but given the extensive work that had already been done, git was seemingly unable to fully merge the commit history without losing the original commit history.
