the download link I have provided is a RTM version (beta is over). installing it will add to your current VS2010 RTM application. The "read me" documents explains it all.

>Thanks for replies.
>I had already seen this or similar sites but was reluctant to sart downloading and installing as it referred to 'Beta' as well as
> 'Visual Studio Exptess' . I have full Visual Studio and thoght that the Phone stuff was out of Beta from last week .
>If anybody could jump in and clarify what the situation is it would be helful.
