The simplest way to do that is by opening the certificate store you want and then using X509Certificate2UI.

var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
var selectedCertificate = X509Certificate2UI.SelectFromCollection(
    store.Certificates, 
    "Title", 
    "MSG", 
    X509SelectionFlag.SingleSelection);

More information in X509Certificate2UI on MSDN.
