Xaml

Hallo zusammen

Ich bin gerade ein bisschen die Grundlagen für XAML am Studieren. Bei Microsoft sind da ein paar brauchbare Ressourcen vorhanden. Nun wenn ich folgenden Code

<Window
Xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
  <Button>Hello, XAML!</Button>
</Window>

kopiere und dann ausführen lassen will erscheint mir dann folgende Fehlermeldung

Alleine für die Darstellung wird noch nicht eine Code-Datei benötigt oder? Wenn ich die Schema Referenz im Header in meinen Browser eingebe, dann sagt mir die Microsoft-Seite, dass diese nicht verfügbar sein.
Kann eventuell dort noch der Fehler liegen?

Danke für die Hilfe.

Das ist kein Fehler in XAML, schau dir mal die Exceptions an.

System.Security.Cryptography.CryptographicException

• The profile for the user is a temporary profile.

Als was für nen User bist du denn angemeldet? Normaler Standarduser?

Eigentlich habe ich lokale Adminrechte.
