Publishing WPF .Net Core 3 app and Serilog.Sinks.File

NuGet package Serilog.Sinks.File gives an error when publishing.

I am trying to publish a self-contained WPF .NET Core 3.0 app. The app builds, runs fine publishes fine until Serilog.Sinks.File is added. Once Serilog.Sinks.File is added to the project, the app builds/runs and even logs correctly. However, when trying to publish this error is given;

System.AggregateException: One or more errors occurred. ---> System.Exception: Publishing failed. --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Microsoft.Publish.Framework.Model.DefaultPublishSteps.<>c__DisplayClass26_0.b__2() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Publish.Framework.Model.DefaultPublishSteps.d__23.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Publish.Framework.ViewModel.ProfileSelectorViewModel.d__205.MoveNext() ---> (Inner Exception #0) System.Exception: Publishing failed.<---

System.Exception: Publishing failed.

===================

Remove Serilog.Sinks.File and the app publishes.

Even removing the Serilog initialize command and the same error occurs.

Did you check the exception(s) inside the AggregateException to see if it gives any clue? – C. Augusto Proiete
@CaioProiete not really, the output in VS, just says Build: 11 succeeded, 0 failed, 0 up-to-date, 0 skipped, then Publish: 0 succeeded, 1 failed, 0 skipped. No actual error in the output. A message box appears pointing to a temp file with the above error message. – Xaphann
Oh that's a shame the log is not flattening the exceptions within the Agg Exception. – C. Augusto Proiete
Long shot: Are you configuring the File log via appSettings.json or app.config? If you are, it's possible the build process is failing to detect the dependency to the File sink... It's worth a quick test... Just put this Console.WriteLine(typeof(Serilog.FileLoggerConfigurationExtensions)); somewhere in the startup of your app, to create a static dependency to the File Sink assembly, and see if that helps. – C.

@CaioProiete found the solution, see below – Xaphann

I found the solution turns out that Serilog.Sinks.File is not the correct Nuget package. You need to use Serilog.AspNetCore and then the app is able to publish.
