Compiler Error C3813

a property declaration can only appear within the definition of a managed or WinRT type

Remarks

A property can only be declared within a managed or Windows Runtime type. Native types do not support the property keyword.

Example

The following example generates C3813 and shows how to fix it:

// C3813.cpp
// compile by using: cl /c /clr C3813.cpp
class A
{
   property int Int; // C3813
};

ref class B
{
   property int Int; // OK - declared within managed type
};
