Compiler Warning (level 4) C4434

a class constructor must have private accessibility; changing to private access

C4434 indicates that the compiler changed the accessibility of a static constructor. Static constructors must have private accessibility, as they are only meant to be called by the common language runtime. For more information, see How to: Define Static Constructors in a Class or Struct.

The following sample generates C4434.

// C4434.cpp
// compile with: /W4 /c /clr
public ref struct R {
   static R(){}   // C4434
