Compiler Error C2866

'variable' : a const static data member of a managed type must be initialized at the point of declaration

It is invalid to declare an uninitialized, conststatic data member in a managed class or struct.

The following sample generates C2866:

// C2866.cpp
// compile with: /clr /c
ref class x {
   const static int i;   // C2866
   const static int j = 0;   // OK

   // Delete the following line to resolve.
   void xx() { i = 9; }

The following sample generates C2866:

// C2866b.cpp
// compile with: /clr:oldSyntax /c

__gc class CMyClass {
   const static double d;   // C2866
   const static double d2 = 9;   // OK
