ConstructorInfo GetCustomAttributes different implementations

Question

In a class library that targets Windows 8.1 and Windows Phone 8.1 I have the following code, where the GetCustomAttributes returns IEnumerable<Attribute>.

int amountOfParams = constr[x].GetCustomAttributes(true).Count();

In my universal app I imported the library in the Windows and in the Windows Phone project if I open the class here I see that the same line returns an Object[].

So I tried to fix it with preprocessor directives like this:

#if WINDOWS_PHONE_APP
            int amountOfParams = constr[x].GetCustomAttributes(true).Length;
#else
            int amountOfParams = constr[x].GetCustomAttributes(true).Count();
#endif

But this doesn't work it always chooses the else, I also noticed that in VS2013 update 4 the drop down box that specifies how to view the code only lists (Miscellaneous Files).

Is there a way to fix this problem?

With kind regards,

Make sure that your project contains the conditional compilations symbols NETFX_CORE and WINDOWS_APP under Project->Properties->Build->General.
