-    When compiling without mono, but targeting mono we need to replace some assemblies with facades to make it run on mono.
-    This MonoFacades.targets file should only be included if not targeting windows and targeting net4x.
-  
-    Warning: We ONLY support facades that reside directly in MonoFacadesPath, otherwise the joining of items becomes complicated.
-
-    Any MonoFacade listed that doesn't exist on disk will be removed instead of replaced.
-
-    See: https://github.com/mono/mono/blob/master/tools/nuget-hash-extractor/download.sh
-    That list defines assemblies that are prohibited from being loaded from the appdir, instead loading from mono GAC.
