Probléme avec TestProject.

Bonjour,
en faite j'ai crée un nouveau Projet de Test pour mon application,
et que je voulais builder, il me sorte 3 erreurs:


Error 20 The "ResolveManifestFiles" task failed unexpectedly.
System.ArgumentException: Illegal characters in path.
at System.Security.Permissions.FileIOPermission.HasIllegalCharacters(String[] str)
at System.Security.Permissions.FileIOPermission.AddPathList(FileIOPermissionAccess access, AccessControlActions control, String[] pathListOrig, Boolean checkForDuplicates, Boolean needFullPath, Boolean copyPathList)
at System.Security.Permissions.FileIOPermission..ctor(FileIOPermissionAccess access, String[] pathList, Boolean checkForDuplicates, Boolean needFullPath)
at System.IO.Path.GetFullPath(String path)
at Microsoft.Build.Tasks.Deployment.ManifestUtilities.Util.RemoveDuplicateItems(ITaskItem[] items)
at Microsoft.Build.Tasks.ResolveManifestFiles.set_NativeAssemblies(ITaskItem[] value)

Error 21 The "NativeAssemblies=@(NativeReferenceFile);@(_DeploymentNativePrerequisite)" parameter for the "ResolveManifestFiles" task is invalid.

Error 22 The "ResolveManifestFiles" task could not be initialized with its input parameters.

Clicking one of the 3 items in the error list brings up this section in Microsoft.Common.targets:

<!-- Create list of items for manifest generation -->
<ResolveManifestFiles NativeAssemblies="@(NativeReferenceFile);@(_DeploymentNativePrerequisite)">
<Output TaskParameter="OutputAssemblies" ItemName="_DeploymentManifestDependencies"/>
</ResolveManifestFiles>

Merci de votre aide
