Another workaround is to set IncludeAllContentForSelfExtract to true when publishing. Setting this property to true changes the .NET 5.0 system of single-file apps to be backward compatible with the .NET Core 3.x system (as described here).

I have tested this with version 3.2.0-dev-00264 of Serilog.Settings.Configuration and it works; version 3.1.0 will not work.

Some additional info on the workaround can be found here - https://github.com/dotnet/runtime/issues/44511#issuecomment-725253197 Related issue - https://github.com/dotnet/runtime/issues/42265
