Unresolved external symbol UMaterialExpressionFresnel::GetPrivateStaticClass(wchar_t const *)

In UE 4.10, the following statement

UMaterialExpressionFresnel::StaticClass();

will result in a link error:

error LNK2019: unresolved external symbol "private: static class UClass * __cdecl UMaterialExpressionFresnel::GetPrivateStaticClass(wchar_t const *)"

According to the answer to the thread Using NewObject With USplineComponent, Compiler Linker Error, USplineComponent::GetPrivateStaticClass - Programming & Scripting - Epic Developer Community Forums this kind of error needs only a simple fix. How to fix it myself?

I have the same issue with Rotator!
