You also need to accept hot modules in your app code.,Hot Module Replacement allows to add, change or delete app module when application is running. Page reloading is not needed in this case., Add Hot Module Replacement (HMR)

Simply update configuration of UseWebpackDevMiddleware with new options:

app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions() {
   ConfigFile = "webpack.config.js", //this is defualt value
      HotModuleReplacement = true,
      ReactHotModuleReplacement = true, //for React only
});

Create a new ASP.NET Core Web Application project and use the React.js and Redux template. Use .NET Core and ASP.NET Core 3.0 settings also., Ask questionscreate-react-app 3.3 breaks HMR and linting ,create-react-app 3.3 was released today with support for typescript 3.7.0 features. After updating react-scripts to 3.3.0 and typescript to 3.7.3, HMR and linting stopped working. If I run npm run start from the command line, everything works as normal. This functionality stopped working when running through visual studio launching the web page via spa.UseReactDevelopmentServer(npmScript: "start").
