Hi,

I'm afraid we can't reproduce this problem (Properties failed less than zero). Please try to install last updates to your workstation and turn UAC off (Control Panel>User Accounts).

Thank you, Marina

version 8.2.4.0 worked fine
the problem showed after upgraded to 8.2.6.0...
after my workstation the same thing happened to my laptop (vs2008 sp1, vista 32 business,silverlight tools instaled)
so it has to be more than a random fault..

please check again...
I cant work no more

xaml power tools...

Hi,

Let me explain how the XAML Toys add-in works. You drop a control onto the Form, and assemblies are added to your project. The XAML Toys add-in parses the assembly name. Our design-time assemblies have short names, i.e. DevExpress.XtraEditors.v8.3.Design. However, the XAML Toys parses an assembly name as if it is a full name:

[VB.NET]

Private Shared Function CurrentDomain_AssemblyResolve(ByVal sender As Object, ByVal args As ResolveEventArgs) As
Assembly

        Dim strFileName As String = String.Empty

        If args.Name.Contains("\") Then
            strFileName = args.Name

        Else
            strFileName =
System.IO.Path.Combine(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly.Location),
args.Name.Substring(0, args.Name.IndexOf(","c)) + ".dll")'<-------------Error!
        End If

        If System.IO.File.Exists(strFileName) Then
            Return Assembly.LoadFrom(strFileName)

        ElseIf Assembly.GetExecutingAssembly().FullName = args.Name Then
            Return Assembly.GetExecutingAssembly

        Else
            Return Nothing
        End If

    End Function

Marked line is the cause of the exception. It's necessary to check whether the assembly name is full or short, for example:

[VB.NET]

If args.Name.IndexOf(',') = -1 Then
    strFileName = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly.Location), args.Name +
".dll");
Else 
   strFileName = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly.Location),
args.Name.Substring(0, args.Name.IndexOf(',')) + ".dll");
End If

Thank you, Marina
