runtime/runtime.m

 		"PINVOKE_OVERRIDE",
+#endif
 		"TRUSTED_PLATFORM_ASSEMBLIES",
-		"NATIVE_DLL_SEARCH_DIRECTORIES",


Why is NATIVE_DLL_SEARCH_DIRECTORIES removed? It doesn't look related to R2R (it's also removed for Mono).

We should revert that. I see it’s used for P/Invoke path resolution. I tried to reduce the scope when testing R2R and it wasn't needed for the MAUI sample.
