aspnetcore-browser-refresh.js:55 Unknown payload: { "type" : "Ping" }

Question

aspnetcore-browser-refresh.js:55 Unknown payload: { "type" : "Ping" }

Hedelin Staffan 46

Visual Studio 2022 17.3.0 hot reload I get this error very often. Both in Edge (Version 100.0.1185.44 (Official build) (64-bit)) and Chrome (Version 104.0.5112.81 (Officiell version) (64 bitar))
Most irritating since it's not updating page after save.

asp.net core 6 MVC web project.

I know this older, but I'm using VS Pro Version 17.6.5 and it is still happening.

Hi @Steffes, Timothy (T.)

As you said, this is too older, I suggest you can create a new thread about this problem, and tell us your VS version, application version, browser version and the relates code to reproduce the problem, then it is easier for us to help you. Thanks for your understanding.

VS Pro Version 17.6.5. Chrome Version 116.0.5845.180 (Official Build) (32-bit)

Reproducing the error is really easy

Create a new project - ASP.NET Core Web App (MVC) / .NET 6 (LTS)

Run the project (F5)

In the browser, open Developer Tools (inspect, or F12)

In Visual Studio, open site.js

Add console.log("Hello world!");

Save

Watch the console window closely as you save because the error message goes away very quickly because the page reloads

This happens when debugging. When using dotnet watch this issue does not happen. The problem prevents hot reload working whilst debugging.

Still an issue with 17.3.6 and not just with Hot reload.
It happens to me when a page redirects in a post.
