First of all, congratulations for this great project.

The react net core template (dotnet new react) has a hot reloading feature that it is activated in the development environment using UseWebpackDevMiddleware

To activate this environment is needed to define this environment variable: SET ASPNETCORE_Environment=Development and configured like this:

            if (env.IsDevelopment ()) {
                app.UseDeveloperExceptionPage ();
                app.UseWebpackDevMiddleware (new WebpackDevMiddlewareOptions {
                    HotModuleReplacement = true,
                    ReactHotModuleReplacement = true
                });
            } else {
                app.UseExceptionHandler ("/Home/Error");
            }

It runs fine when running it with dotnet run, however, there is an error thrown when it is started with dotnet electronize start. I think the problem is related to the content root folder.

With dotnet run the content root folder is: C:\Users\pedro\Documents\Projects\crypto.experiments\Crypto.NetCore.GUI (project root)
With dotnet electronize start the content root folder is: C:\Users\pedro\Documents\Projects\crypto.experiments\Crypto.NetCore.GUI\obj\Host\bin\ (executable folder)
