Debugging a React App and ASP.Net MVC 5 API in VS 2019

Is there a simple way to start the React dev server (react-scripts start) and debug a back-end ASP.Net MVC 5 app at the same time in Visual Studio 2019?

With ASP.Net Core, it's a simple call to spa.UseReactDevelopmentServer(npmScript: "start");, but this isn't available in .Net Framework 4.6.

Currently, I can go to the ClientApp folder in my solution, go to the command line and run npm start which will start the React dev server on http://localhost:3000. Any of the AJAX calls end up going to the same port, but the backend is running in IISExpress on a completely different port.
