Host as sub application in IIS

[sandves]

I have recently migrated my application from RC1 to 1.0.0-preview2-final, and I am no longer able to host the app as a sub application under the main website like I was before ("corep" is the application I have migrated):

After the migration, the web.config has moved from the wwwroot and up one level to the content root. Therefore, I changed the physical path of the IIS application accordingly. My web.config is listed below.

<?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=".\Corep.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
  </system.webServer>
</configuration>

I have the following code in my Startup.cs to enable hosting the application as a sub site.

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.Map("/corep", (app1) => this.Configure1(app1, env, loggerFactory));
}

public void Configure1(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();
    app.UseApplicationInsightsRequestTelemetry();
    app.UseApplicationInsightsExceptionTelemetry();
    app.UseStaticFiles();
    app.UseMvc();
}

Application logs tells me that the application is running and requests are received, but every request result in a 404 response. Below is the output from the application when I try to access the index page.

Hosting environment: Production
Content root path: D:\Web\StoragePortal\Corep
Now listening on: http://localhost:9820/corep
Application started. Press Ctrl+C to shut down.
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 GET http://{my-url}/corep/index.html  
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
      Request finished in 160.1519ms 404 

Any ideas about how I can make this work?

EDIT: I just wanted to add that the application works perfectly if it hosted alone, and not as a sub application.

The Map workaround it's no longer required for this scenario, try removing it.

That seemed to do the trick! Now I only need to fix URL rewriting to make the AngularJS work, but that is probably a different issue.

Yeah: aspnet/IISIntegration#192 (comment)
