-    This file contains Runtime Directives, specifications about types your application accesses
-    through reflection and other dynamic code patterns. Runtime Directives are used to control the
-    .NET Native optimizer and ensure that it does not remove code accessed by your library. If your
-    library does not do any reflection, then you generally do not need to edit this file. However,
-    if your library reflects over types, especially types passed to it or derived from its types,
-    then you should write Runtime Directives.
-
-    The most common use of reflection in libraries is to discover information about types passed
-    to the library. Runtime Directives have three ways to express requirements on types passed to
-    your library.
-
-    1.  Parameter, GenericParameter, TypeParameter, TypeEnumerableParameter
-        Use these directives to reflect over types passed as a parameter.
-
-    2.  SubTypes
-        Use a SubTypes directive to reflect over types derived from another type.
-
-    3.  AttributeImplies
-        Use an AttributeImplies directive to indicate that your library needs to reflect over
-        types or methods decorated with an attribute.
-
-    For more information on writing Runtime Directives for libraries, please visit
