Renders contents of the specified file. Example if having a flat file containing a special setting value.

Platforms Supported: All (Removed with NLog v6 - Instead setup custom layout-renderer with method-delegate)

${file-contents:encoding=Encoding:fileName=Layout}

• encoding - Encoding used in the file.Encoding
• fileName - Name of the file.Layout

If the file content doesn't change, then adding the option :cached=true will give a performance boost.
