When enable "Compile with .net native tool chain" the reflection will fail ,how to resolve it

Question

I wrote a UWP app ,and added the following code ,then enable "Compile with .net native tool chain" ，it will return null.

here is the code snippet;

void Test()

{

PropertyInfofieldInfo = typeof(Delegate).GetTypeInfo().GetDeclaredProperty("Method");

}

fieldInfo will be null .

Seems need to modify default.rd.xml ,but whatever I modified ,it always failed . How to resolve it ?

Thanks very much
