I was trying to use UseProxyToSpaDevelopmentServer option from inside of local service fabric cluster and I got no results. I literally didn't get any requests from server, when I was trying to access SPA application by route http://localhost:9000/UI/. I'm using asp.net core 2.1 angular template. I use Razor to create an initial Angular page.

My Startup class looks like:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

    {

        if (env.IsDevelopment())

        {

            app.UseDeveloperExceptionPage();

        }

        else

        {

            app.UseExceptionHandler("/Error");

        }



        app.UseStaticFiles();

        app.UseSpaStaticFiles();



        app.UseMvc(routes =>

        {

            routes.MapRoute(

                name: "default",

                template: "{controller}/{action=Index}/{id?}");

        });



        app.UseSpa(spa =>

        {

            // To learn more about options for serving an Angular SPA from ASP.NET Core,

            // see https://go.microsoft.com/fwlink/?linkid=864501

            spa.Options.SourcePath = "ClientApp";



            if (env.IsDevelopment())

            {

                spa.UseProxyToSpaDevelopmentServer("http://localhost:4200/");

            }

        });

    }

I'm running application in development mode for sure.
I tried to get any request by launching basic node js server as well as angular app with ng serve command, but as I said got no results.

I actually figured it out. The problem is app.UseSpa is coming after app.UseMvc. Since my razor page has been called Index.cshtml, MVC is taking over Spa requests.
