Configuration Syntax

${basedir:dir=String:file=String:processDir=boolean}

dir - Name of the directory to be Path.Combine()'d with the base directory.
file - Name of the file to be Path.Combine()'d with the base directory.
processDir - Introduced in NLog 4.4.2. Render the base directory of the current process? Default false.

Alternative one can use the ${processdir} introduced with NLog v4.7.1
fixTempDir - Enable automatic fallback to processDir when detecting AppDomain.BaseDirectory is temp-directory. Workaround for single-file-publish on NetCore 3.1, and no longer needed with .NET 6.
