Hi Ivan

Did you follow the information here: https://doc.dynamicweb.dev/documentation/fundamentals/setup/hosting/running-in-IIS.html

503 is service unavailable. You have to look in event viewer in Windows to figure out what can be wrong.

You have to show your entire setup if you want us to guess what could be wrong in your setup...

Hi Nicolai

I did. I did not add host name since I wont to use localhost!

This is my web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments="C:\inetpub\wwwroot\HelardiDW10\DyW10 - Heraldi.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
  <system.web>
    <customErrors mode="On" />
  </system.web>
</configuration>

Hi Ivan

And what did your Windows Event Log say?

Did you check this: https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/hosting-bundle?view=aspnetcore-8.0

Try to install the Visual C++ Redistributable which is listed as a requirement - it could be missing from your installation.

This is from log:

Application 'C:\inetpub\wwwroot\HelardiDW10\' started successfully.

Category: Microsoft.Extensions.Hosting.Internal.Host
EventId: 9

BackgroundService failed

Exception: 
System.UriFormatException: Invalid URI: The hostname could not be parsed.

The HostOptions.BackgroundServiceExceptionBehavior is configured to StopHost. A BackgroundService has thrown an unhandled exception, and the IHost instance is stopping. To avoid this behavior, configure this to Ignore; however the BackgroundService will not be restarted.

I did and backend is working now ok but on frontend I get only "No layout selected for website" text,

Thank you very much for your effort!

Ivan

It looks like my Files folder is not published to publish folder!

Ivan

Was that a question? Or did you get it to work?

Hi Nicolai

No. This was constatation and after that I make it work! Thank you!

I am getting this error in log and cannot save anything form backend:

"[2024-03-14 09:43:56.894] C:\inetpub\wwwroot\DW10\HeraldiDW10\runtimes\win\lib\netcoreapp2.1\System.Data.SqlClient.dll Unable to load one or more of the requested types.Could not load type 'SqlGuidCaster' from assembly 'System.Data.SqlClient, Version=4.6.1.6, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' because it contains an object field at offset 0 that is incorrectly aligned or overlapped by a non-object field."

What is the target framework of the project used for building the assembly? C:\inetpub\wwwroot\HelardiDW10\DyW10 - Heraldi.dll

Check the project and make sure that target is .net 8

<TargetFramework>net8.0</TargetFramework>

Try to manually delete existing /obj and /bin folders from your project and then rebuild.

When creating new projects make sure that you have installed the latest version of Dynamicweb.ProjectTemplates.
