 # Compiler Error C2487
 
 'identifier' : member of dll interface class may not be declared with dll interface
 
 You can declare a whole class, or certain members of a non-DLL interface class, with DLL interface. You cannot declare a class with DLL interface and then declare a member of that class with DLL interface.
+
+The following sample generates C2487:
+
+```cpp
+// C2487.cpp
+// compile with: /c
+class __declspec(dllexport) C
+{
+    __declspec(dllexport) void func() {}   // C2487
+};
+```
+
+To resolve this error, remove the DLL interface on the class or the members.
