Examples

The following code example shows how to examine an application manifest from within a GetManifestCompleted event handler to determine whether the application requires full trust by default.

private bool CheckForFullTrust(XmlReader appManifest)
{
    if (appManifest == null)
    {
        throw (new ArgumentNullException("appManifest cannot be null."));
    }

    XAttribute xaUnrestricted =
        XDocument.Load(appManifest)
            .Element("{urn:schemas-microsoft-com:asm.v1}assembly")
            .Element("{urn:schemas-microsoft-com:asm.v2}trustInfo")
            .Element("{urn:schemas-microsoft-com:asm.v2}security")
            .Element("{urn:schemas-microsoft-com:asm.v2}applicationRequestMinimum")
            .Element("{urn:schemas-microsoft-com:asm.v2}PermissionSet")
            .Attribute("Unrestricted"); // Attributes never have a namespace

    if (xaUnrestricted != null)
        if (xaUnrestricted.Value == "true")
            return true;

    return false;
}

Private Function CheckForFullTrust(ByVal appManifest As XmlReader) As Boolean
    Dim isFullTrust As Boolean = False

    If (appManifest Is Nothing) Then
        Throw New ArgumentNullException("appManifest cannot be null.")
    End If

    Dim xaUnrestricted As XAttribute
    xaUnrestricted = XDocument.Load(appManifest) _
        .Element("{urn:schemas-microsoft-com:asm.v1}assembly") _
        .Element("{urn:schemas-microsoft-com:asm.v2}trustInfo") _
        .Element("{urn:schemas-microsoft-com:asm.v2}security") _
        .Element("{urn:schemas-microsoft-com:asm.v2}applicationRequestMinimum") _
        .Element("{urn:schemas-microsoft-com:asm.v2}PermissionSet") _
        .Attribute("Unrestricted")  ' Attributes never have a namespace


    If xaUnrestricted Then
        If xaUnrestricted.Value = "true" Then
            Return True
        End If
    End If

    Return False
End Function
