如何在IIS上托管基本的ASP.NET Core 2 WebAPI应用程序

Question

I created an application as in subject, just selecting "ASP.NET Core Web Application", ".NET Core", "ASP.NET Core 2.0", "Web API".

This creates a simple application, where the 'default' call, "api/values", returns the JSON array '["value1", "value2"] (with only a minor warning on the browser).

So far so good.

Now I would like to deploy this application on an IIS, just using the FolderProfile, so I build the application, I publish it, and I have this directory with all the files needed to run it. I see that a web.config is added (it is not in the sources), with the correct configuration to start the runtime with the generated dll.

I copy this directory on a physical directory, I create a web site within an application pool, in short, everything, and I configure it as common sense suggests, since I couldn't find any tutorial for ASP.NET Core 2. The docs for Core 1 don't apply correctly, since there are many changes...

In the end I always end up with this result:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

The generated web.config is as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet" arguments=".\Core2WebService.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
  </system.webServer>
</configuration>

I tried whatever I could, but always with this end result... Any ideas? Thanks.

Answer 1

Check Host on Windows with IIS documentation. Right now it looks like you at least forgot to Install the .NET Core Windows Server Hosting bundle .

The bundle will install the ASP.NET Core Module in addition that creates the reverse-proxy between IIS and the Kestrel server.

Answer 2

You can directly publish from your .Net Core application.

I have written a step by step guide for the same, only difference is, I have explained to host the application instead of Web API.
