Blind-bake the pie crust according to package or recipe directions. Cool completely.
In a medium saucepan, combine raspberries, sugar, cornstarch, and water. Cook over medium heat, stirring, for about 5 minutes or until thickened. Remove from heat and cool completely.
In a large bowl, beat cream cheese, powdered sugar, and vanilla until smooth. In a separate bowl, whip heavy cream to stiff peaks. Fold whipped cream into the cream cheese mixture.
Spread the cream layer into the cooled crust. Spoon the cooled raspberry layer over the top.
Refrigerate at least 4 hours, or until set.
Top with whipped cream and fresh raspberries before serving.
