The "ValidateXaml" task failed unexpectedly.

Question

Bonjour, j'ai une erreur lorsque je compile mon projet silverlight. Est ce que quelqu'un pourrait m'aider?

Error 1 The "ValidateXaml" task failed unexpectedly.
System.IO.FileLoadException: Could not load file or assembly 'file:///u:\visual studio 2010\Projects\TEST SL 2\IZI SL 2\obj\Debug\TEST SL 2.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

TEST SL 2 


Je n'ai pas ce probleme sur mon pc portable avec Windows Vista uniquement sur mon pc de travail avec Windows XP, sur lequel était installé la version 2 de silverlight.
Lorsque je lance un nouveau projet et que je selectionne Navigation Application, j'ai ce message d'erreur des la premiere compilation, je vois pas d'où cela peut venir.
En effet je pense que les modeles de Visual Studio 2010 Beta 2 ne comportent pas d'erreur.

Bonjour,

Je pense que ton projet VS2010 est un projet SilverLight 3.
Il faut donc que tu installes SL3 sur ton poste XP.
