IHostApplicationBuilder.UseNLog() is not available for Framework projects

[FixRM]

Hello and thank you for your work!

I use Microsoft.Extensions.Hosting with .NET Framework 4.7/4.8. It turns out that IHostApplicationBuilder.UseNLog() is available only #if NET8_0_OR_GREATER. Updating to .NET 8 is not an option due to other Microsoft dependencies. Is there a simple workaround?

I guess it's builder.Logging.AddNLog(); Sorry to bother you.

p.s. UseNLog implementation for NET8_0_OR_GREATER is still more complicated than line above. Is there any differences between them?

Yes when I updated .NET Framework v4.6.2 to use NET8-nuget-dependencies, then I forgot to add support for IHostApplicationBuilder.

Created #801 to update NET Framework v4.6.2 with UseNLog for IHostApplicationBuilder. Will be included in NLog.Extensions.Logging v6.0.1

There is very little difference between AddNLog() and UseNLog(). The UseNLog() includes a bonus scan for NLog.config in the host-content-root-directory, and also bonus scan for NLog.Environment.config-file.

Believe you can also do this:

    builder.Logging.ClearProviders();   // Remove default providers
    builder.Host.UseNLog();

Thank you! HostApplicationBuilder doesn't has Host property, but builder.Logging.AddNLog() works well without additional configuration. My NLog.config was attached by default

NLog.Extensions.Hosting v6.0.1 has been released, and includes NET Framework v4.6.2 with UseNLog for IHostApplicationBuilder
