El depurador crea una nueva instancia de la clase de proxy de tipo cada vez que necesita mostrar una variable del tipo de destino. Esto puede afectar al rendimiento. Por tanto, en el constructor no debe realizarse más trabajo del estrictamente necesario.

Ejemplos

En el ejemplo de código siguiente se muestra el uso del DebuggerTypeProxyAttribute(Type) constructor para especificar un proxy de visualización del depurador. Este ejemplo de código es parte de un ejemplo más grande proporcionado para la clase DebuggerDisplayAttribute.
