Unity + UWP – How to open the Rate Now Screen
There is a trick here, you need a different conditional define for Mono Builds and another for IL2CPP builds!
Mono Builds
#if NETFX_CORE
string productID = Windows.ApplicationModel.Package.Current.Id.FamilyName;
Application.OpenURL("ms-windows-store://pdp/?ProductId=" + productID);
#endif
IL2CPP Builds
#if ENABLE_WINMD_SUPPORT
string productID = Windows.ApplicationModel.Package.Current.Id.FamilyName;
Application.OpenURL("ms-windows-store://pdp/?ProductId=" + productID);
endif
The real trick is to use the #ENABLE_WINMD_SUPPORT conditional define for IL2CPP builds or #NETFX_CORE for Mono Builds.
