I'll probably make a code release tomorrow evening with bug fixes and a few enhancements to the administration features.

The compile issue is probably because you don't have the ByteFX .NET data provider for MySQL installed. You can get the correct version at http://www.bytefx.com/survey.aspx

The location of the web is determined by VS.NET by looking in the .webinfo file in the root of the web. It should point to http://localhost/mojoportal

The web won't build if the business or data layer doesn't build. Are you saying that the business and data layers both build just not the web? If you are using MS SQL you should remove the MySQLData project from the solution and check the reference under the mojoportal.Business project. If it has a reference to MySQLData, remove it and if it doesn't have a reference to MSSQLData add it as a project reference.

Are you getting a specific error?

That is exactly what would happen if you don't have the virtual directory setup correctly in IIS. On my machine I have the solution at c:\_Projects\mojoportal and http://localhost/mojoportal maps to c:\_Projects\mojoportal\Web

I did that by right clicking the default web site and choosing new Virtual Directory entered mojoportal for the alias and browsed to the folder C:\_Projects\mojoportal\Web

Note that if you mapped it to the mojoportal folder that is incorrect. It must map to the Web folder.
