Databinding Enum - The name 'StoreLocation' does not exist in the namespace

Question

I'm getting a error:

The name 'StoreLocation' does not exist in the namespace "clr-namespace:System.Security.Cryptography.X509Certificates;assembly=mscorlib"

on line:

<x:Type TypeName="crypto:StoreLocation" />

What I'm doing wrong?

        </DataGrid.Columns>
