If you have used a Page that effectively uses a codebehind classname that is the same as say the Login control, that is Login, e.g. your page was called Login.aspx, then when you pre-compile (publish) the web site as an updateable web site, the aspx is retained and tries to compile against a type called Login in the code behind.

Many post and solutions can get from the internet. Among them is

1. Rename Login.aspx to others name like signin.aspx
   
2. Try using a classname for your codebehind and defined in the inherits that does not clash with a type in System.Web, e.g. LoginPage, or qualify the class and therefore the inherits statement with a namespace, e.g.<%@ page ... inherits="theNs.Login" %.namespace theNs { public partial class Login : System.Web.UI.Page { .. } }
   
3. uncheck “Allow this precompiled site to be updatable” when Publish Web Site in Visual Studio 2005.

Solution no. 3 is good for me. Less work and works 100%.
