2. In the Startup.cs, you will need to add the following namespace.
using Microsoft.AspNetCore.Mvc;
3. In the Startup.cs, there are two methods.
ConfigureServices
Inside this method, you will have to add the following code which will instruct the program to add MVC and Razor Pages Services along with version compatibility.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
Configure
Inside this method, the default settings for the Razor Pages are configured.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseCookiePolicy();
app.UseMvc();
}
Now press F5 to run the Application and you should see a blank page in browser.

Displaying a Message from Controller to View in ASP.Net Core 2.0 Project
1. Inside the Razor PageModel class, OnGet handler method, the public property Message is set.
public class IndexModel : PageModel
{
public string Message { get; set; }
public void OnGet()
{
this.Message = "This is my First ASP.Net Core Razor Page";
}
}
2. Then inside the Razor HTML Page, the public property Message is accessed from the Razor PageModel class and displayed.
@page
@model Core_HelloWorld.Pages.IndexModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width"/>
<title>Index</title>
</head>
<body>
<h3>@Model.Message</h3>
</body>
</html>
