ASP.NET 核心空白应用startup.cs

Question

I am trying to follow along with a pluralsight course creating in VStudio 2019 a blank ASP .NET core project with an empty project template.

My startup.cs differs significantly from the course in that it does not have

app.UseRouting() and app.useEndpoints()

my startup.cs basically has only app.Run()

I recreated project 2 times to make sure I followed directions, I made sure my.Net Core and CLR were the most recent versions. Google search revealed no useful information. I assume I am missing something fundamental. I made sure I created like course did use blank solution and empty project template.

My newly created solution runs fine so I presume there is some "version problem" or something changed in terms of the way things are done?

Thanks much

Sounds like you have done something wrong as if you look at the doco

All ASP.NET Core templates include routing in the generated code. Routing is registered in the middleware pipeline in Startup.Configure.

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapGet("/", async context => { await context.Response.WriteAsync("Hello World;"); }); }); }

This is with Core 3.1 - check the verson of Core app you are creating.
