Question: (Warning - asp newbie) I have an aspx file with the tag

```
    <%@ Page Language=VB  ... %>

```

right at the beginning of the file.

When calling this from my IIS server (<http://localhost/myservice/default.aspx>), this gives me the error 

> 
> This page contains the following
>  errors:

What am I doing wrong?

Answer: 
When I went into the ASP.NET tab for the virtual directory I noticed the ASP.NET version was not selected (it was an empty combo box). Choosing the .NET framework version did the trick. Thanks.
For me, the problem was in the serialization that responded to client.

My problem was in the xml tags spaces:

```
  - < tag > text < / tag >  ---> wrong

  - <tag> text </tag> ----> good.

```
