Compiler Error C3153

'interface' : you cannot create an instance of an interface

An interface cannot be instantiated. To use the members of an interface, derive a class from the interface, implement the interface members, and then use the members.

The following sample generates C3153:

// C3153.cpp
// compile with: /clr
interface class A {
};

int main() {
   A^ a = gcnew A;   // C3153
}
