I was reading my new asp.net book last night and thought I'd give mobile
devices a go.

I use Web Matrix, however when I went to create a new mobile page this
morning, it displayed a dialog box with the message:
"specified cast is not valid"

The file seems to be getting created, but does not open. I get the same
error when I try to open the file too.

I'm sure when I first installed Web Matrix I created a mobile page and
everything worked fine.


I have tried reinstalling Web Matrix but this had no effect.

Hi Kevin,

We in this newsgroup know few from the WebMatrix; when you speak Portugese
there is a special newsgroup for it. I assume not and than I think the best
newsgroup as an alternative is

microsoft.public.dotnet.framework.aspnet

Although when you are sending the sentence which give the error I am sure
that someone here will will look if he/she can help you.
