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