.NET Core app targeting full framework - Stopped working in IIS

We have a ASP.NET Core MVC application that targets net461 due to requiring Entity Framework for Oracle.
Up until recently, this application has been working fine on both our DEV and QA servers.
We are deploying it as a self-contained app, but also have .NET Core runtime and the ASP.NET Core IIS hosting bundle installed on the servers.
Recently, we started running into issues after deployment where the application will not start up. In the browser, we get 502.5 Process Failure.
On the server, the only error we can find is in the Windows event logs: Application 'MACHINE/WEBROOT/APPHOST/DEFAULT WEB SITE/<appname>' with physical root 'D:path' created process with commandline 'D:path<appname>.exe ' but failed to listen on the given port '<randomport>'.
Various SO posts and articles I have found say this is usually due to a different runtime version installed on the server vs. the client.
This is self-contained so the runtime is bundled, so I'm not sure that is the issue.
We have not changed what is installed on our development PCs OR on the servers, but have tried uninstalling and re-installing the runtime on the servers.
Since this targets the full framework
net461does it even matter the .NET Core version? Or does only the .NET version matter?
We have some people thinking the issue is with it obtaining a port to listen on. I have tried adding .UseUrls() in Program.cs and adding in Kestrel ports in appSettings.json but nothing makes any difference and we still get the same error.
To make matters more confusing, our current build runs fine on the QA server now but fails to start in DEV. Sometimes we try to publish and it works in one environment but not the other, and sometimes it fails in both. We are following the same deployment steps and the only differences are config files.
We have tried <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest> and without.
We have tried publishing from VS and from dotnet publish.
We have tried net stop was /y net start w3svc.
We even had the server restored to an earlier point before these issues started.
As of now, we can't find any pattern to when/why some deployments will run and some will fail. Is there anyone who can provide some input on this?

It sounds like the app is throwing an exception during startup. Try opening a command prompt to the published app directory and runningdotnet MyApp.dll. If you see any exceptions logged to the console window, please update your question with those, along with the stack traces.

It is an .exe file, so there is no .dll. If I try this locally, it takes a minute but eventually starts up. If I try it on the server, it just hangs and nothing shows in the console window.

Mar 27 at 12:39
Sorry. I read that, but it didn't sink in. Running the exe has the same effect of what I was looking for though. If it's hanging, you might be timing out on a connection or something. You might need to add some more extensive logging around yourStartupclass.

That's not a bad idea. If I setstdoutLogEnabled="true" stdoutLogFile=".logsstdout"in my web.config, log files are created there but are never written to. I'll manually try someFile.WriteAllText()s and see if I can't get anything that way.

ILoggerFactoryis a hosting service, so it can be injected intoStartup(as well as more specific logging interfaces such asILogger<Startup>). In short, you can add anILogger<Startup>param to yourStartupconstructor, save it to an ivar and then utilize it inConfigureServicesandConfigure. That should make your logging efforts much easier.

On application startup, we are scheduling some things using FluentScheduler. On had a start/end time that must be confusing the library. It causes it to freeze up entirely without throwing an exception. Removing/changing the time fixed or issue!

Log statements. Put them everywhere in Program.cs and Startup.cs and log things to file. From there we just looked at what did and didn't log to narrow down where it was stopping.

It sounds like the app is throwing an exception during startup. Try opening a command prompt to the published app directory and running
dotnet MyApp.dll. If you see any exceptions logged to the console window, please update your question with those, along with the stack traces.– Chris Pratt

It is an .exe file, so there is no .dll. If I try this locally, it takes a minute but eventually starts up. If I try it on the server, it just hangs and nothing shows in the console window.

Sorry. I read that, but it didn't sink in. Running the exe has the same effect of what I was looking for though. If it's hanging, you might be timing out on a connection or something. You might need to add some more extensive logging around your
Startupclass.– Chris Pratt

That's not a bad idea. If I set
stdoutLogEnabled="true" stdoutLogFile=".logsstdout"in my web.config, log files are created there but are never written to. I'll manually try someFile.WriteAllText()s and see if I can't get anything that way.– neilsimp1

ILoggerFactoryis a hosting service, so it can be injected intoStartup(as well as more specific logging interfaces such asILogger<Startup>). In short, you can add anILogger<Startup>param to yourStartupconstructor, save it to an ivar and then utilize it inConfigureServicesandConfigure. That should make your logging efforts much easier.– Chris Pratt
