This is not an answer. The above answers above do not seem to work in .Net8 hence my request for help.

I have upgraded to .NET 8. Have also upgraded Serilog.AspNetCore(8.0.3) Serilog.Extensions.Hosting (8.0.0) But I get the error described above.

'IWebHostBuilder' does not contain a definition for 'UseSerilog' 

my code: " webBuilder.UseStartup() .UseConfiguration(Configuration) .UseSerilog();"
