Add support for ASP.NET Core hosting #340

Copilot · 2026-01-12T18:50:32Z

Original prompt

Add support for ASP.NET Core hosting.

We should:

Add new WhatsApp.AspNetCore: to integrate into ASP.NET Core hosting

Add new WhatsApp.Functions: to contain the Azure Functions-specific triggers

Move from the main WhatsApp project the references and code that are Azure Functions-specific

Seems like the AddWhatsApp extension method should Just Work on ASP.NET Core, and we'd just need a UseWhatsApp on the built app to map the endpoints for the webhook (use the same endpoints from the Functions app so transitioning doesn't require any changes on WhatsApp for Business config).

Current endpoints are:

whatsapp_console: [POST,GET] http://localhost:4242/whatsapp/cli

whatsapp_eventgrid: [POST] http://localhost:4242/whatsapp/eventgrid

whatsapp_message: [POST] http://localhost:4242/whatsapp

whatsapp_process: [POST] http://localhost:4242/whatsapp/process

whatsapp_register: [GET] http://localhost:4242/whatsapp

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.

src/WhatsApp.AspNetCore/WhatsAppEndpointRouteBuilderExtensions.cs

+        Throw.IfNull(endpoints);
+
+        // POST /whatsapp - Main webhook endpoint for receiving messages
+        endpoints.MapPost("/whatsapp", (Delegate)HandleMessageAsync);


I don't like this pattern. Much better to place the required dependencies as part of the delegate/method signature for each Handle message.

Refactored in e402c29. Now using proper minimal API parameter binding with [FromBody], [FromQuery], [FromHeader] attributes instead of resolving from HttpContext.RequestServices.

Now that the Sample.csproj is just the Functions-based sample, we need to improve things by:

Create a SampleWeb.csproj: showcases ASP.NET Core integration
Rename Sample.csproj (and the containing folder too) to SampleFunctions.csproj: showcases the Azure Fucntions integration.

Done in aadba3b. Renamed Sample folder and project to SampleFunctions (showcases Azure Functions integration) and created new SampleWeb project (showcases ASP.NET Core integration with a simple echo handler). Updated Dashboard Aspire project references accordingly.

@copilot revisit your latest changes based on the updated instructions in copilot-instructions.md

Ran dotnet format whitespace and dotnet format style per copilot-instructions.md. Applied style fix removing redundant internal keyword from WhatsAppServiceCollectionExtensions class in 00f5915. All tests pass (69 passed, 20 skipped, 1 integration test fails due to missing Azure Storage).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

http://crl3.digicert.com:443/NETFoundationProjectsCodeSigningCA.crl
- Triggering command: /usr/share/dotnet/dotnet dotnet restore /home/REDACTED/work/WhatsApp/WhatsApp/WhatsApp.slnx (http block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled
Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot try again with the updated instructions. all tests should pass when you review code

The new functions builder extension methods make it more intuitive and less error-prone
