Hello, I'm new to ASP.NET, but have experience working with .NET applications.

I'm following the instructions, creating empty ASP.NET Core 3.1 project and it is built and deployed correctly, BUT then I cannot see "Go to my application" button. And if I go to {myApp}.apphb.com in chrome I get "Welcome to ngiinx" page.

Also, I am running a telegram bot in my application and it seems to work fine and be responding.
So the question is, how do I visit my site, where can I get the link to my application?

   Just to give you some more information.

   I created the same empty application, but using .NET Framework 4.8 instead of .NET Core and everything seems to be working just fine.

   So, I believe the problem is not fully implemented support of .NET Core.
   Is it possible to fix this issue?

   Hi,

   .NET Core 3.1 is supported but still requires publishing to the output directory using a bit of configuration in your web project file. All current versions of the .NET Core runtime are installed on the worker and build servers, including the dev SDKs, ASP.NET Core runtimes etc.

   This is different from "regular" .NET Framework apps as you also described; for .NET Core apps you'll need to trigger the Publish build target and set the PublishDir project property on the relevant web project yourself to make sure it's published in a way that's compatible with AppHarbor. That's pretty straightforward as you can see in this sample csproj file (for an older .NET Core version, but the build target and publish directory configuration also applies for newer versions):

   <Project Sdk="Microsoft.NET.Sdk.Web" DefaultTargets="Publish">
       <PropertyGroup>
           <TargetFramework>netcoreapp1.1</TargetFramework>
           <PublishDir>$(OutDir)_PublishedWebsites\NetCoreApp\</PublishDir>
       </PropertyGroup>
       <PropertyGroup>
           <PackageTargetFallback>$(PackageTargetFallback);portable-net45+win8+wp8+wpa81;</PackageTargetFallback>
       </PropertyGroup>
       <ItemGroup>
           <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" />
           <PackageReference Include="Microsoft.AspNetCore" Version="1.1.2" />
           <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.3" />
           <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.2" />
           <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.2" />
           <PackageReference Include="Microsoft.VisualStudio.Web.BrowserLink" Version="1.1.2" />
       </ItemGroup>
       <ItemGroup>
           <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="1.0.1" />
       </ItemGroup>
   </Project>
   

   Your website project should be published when you make these couple of changes to the web project file, commit it to your repository and push to AppHarbor, but let me know if you continue to experience issues with this!

   Cheers,
   Rune

   Thanks! Everything worked just fine!

   For everyone wondering, my empty .csproj looked like:
   <Project Sdk="Microsoft.NET.Sdk.Web">
       <PropertyGroup>
           <TargetFramework>netcoreapp3.1</TargetFramework>
       </PropertyGroup>
   </Project>

   So, I followed the instructions and now it looks like this:
   <Project Sdk="Microsoft.NET.Sdk.Web" DefaultTargets="Publish">
       <PropertyGroup>
           <TargetFramework>netcoreapp3.1</TargetFramework>
           <PublishDir>$(OutDir)_PublishedWebsites\NetCoreApp\</PublishDir>
       </PropertyGroup>
   </Project>

   Thanks, Rune!
