<!--
|
||||
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.
|
||||
|
||||

|
||||
