problem starting Cassini

Hi I'm very new to Cassini and ASP.NET. I downloaded Cassini, compiled it and started it like this : Application Directory = c:\cassini\www\ Port = 80 Virtual Root = / I made a default.aspx page in my www directory. When I try to access it with http://localhost/, I have the message below (in french). Where does it come from ? I'm lost, help ! Thanks :) --------------------------------------------------------------------------- Erreur du serveur dans l'application '/'. La référence d'objet n'est pas définie à une instance d'un objet.

Re: problem starting Cassini

Does the page work if it's served by IIS and not Cassini? What are the contents of your "default.aspx" page? This posting is provided "AS IS" with no warranties, and confers no rights.

Re: problem starting Cassini

I don't own IIS. But I tried to launch this page with the server included in Web Matrix, and it works fine. Here is the content of my default.aspx (it's just a page I took from there) : ------------------------------ <script runat="server"> void ValidateBtn_Click(Object Sender, EventArgs E) { if (Page.IsValid == true) { lblOutput.Text = "Page is Valid!"; } else { lblOutput.Text = "Some of the required fields are empty"; } } </script>

Re: problem starting Cassini

Strange since the Web Matrix server is the same app as Cassini. Its just one is fired up via Web Matrix and the other you launch from a command prompt. I loaded Cassini outside of Web Matrix and was able to serve your page just fine. Do you get this failure for all pages or just this page? When you first built Cassini using "build.bat", did it report any errors? This posting is provided "AS IS" with no warranties, and confers no rights.
