WebviewBind (NuGet Package)

WebviewBind is a C# source generator package that creates WebView2 host-side dispatch code for methods marked with [WebviewExport].

Install

dotnet add package WebviewBind

What It Generates

For each partial class marked with [WebviewContainer], the generator emits:

  • RegisterWebviewHandler(CoreWebView2 coreWebView2) to attach message handling.
  • JSON call deserialization and method dispatch.
  • Support for sync return values, Task, and Task<T> methods.
  • Error propagation back to JavaScript response payload.

Quick Start

1. Mark host container class

[WebviewBind.WebviewContainer]
public partial class MainWindow : Window
{
}

2. Export host methods

[WebviewBind.WebviewExport]
private string GetGreeting(string userName)
{
    return $"Hello {userName}!";
}

[WebviewBind.WebviewExport]
private async Task<string> GetMessageAsync(string arg)
{
    await Task.Delay(1200);
    return $"{arg}, async reply from host.";
}

3. Register handler after CoreWebView2 is ready

await WebView.EnsureCoreWebView2Async();
RegisterWebviewHandler(WebView.CoreWebView2);

4. Call from JavaScript

const greeting = await InvokeHostMethod('GetGreeting', 'Alice');
const asyncResult = await InvokeHostMethod('GetMessageAsync', 'WebView');

JavaScript Call Contract

Request payload:

{
  "callId": "string",
  "method": "GetGreeting",
  "args": ["Alice"]
}

Response payload:

{
  "callId": "string",
  "result": "Hello Alice!",
  "error": null
}

Supported Method Shapes

  • void Method(...)
  • T Method(...)
  • Task Method(...)
  • Task<T> Method(...)

Notes

  • Export methods should be instance methods on a class marked with [WebviewContainer].
  • Parameters and return values must be JSON-serializable.
  • Unknown method names return an error response.
