SYMPTOMS

Consider the following scenario:
  • You create a Microsoft ASP.NET 2.0 application.
  • ASP.NET 2.0 is configured to run with a user account.
  • The SerializeAs attribute of the Profile property in ASP.NET 2.0 is set to Xml.
In this scenario, ASP.NET 2.0 may not save the user profile, and you may receive an error message that is similar to the following:
[InvalidOperationException: Unable to generate a temporary class (result=1).
error CS2001: Source file 'D:\WINDOWS\TEMP\d0lurtzx.0.cs' could not be found

CAUSE

This issue occurs if the user account does not have the List Folder Contents and Read permissions on the %windir%\Temp folder.

RESOLUTION

To resolve this issue, grant the user account the List Folder Contents and Read permissions on the %windir%\Temp folder.

          bool   fPersist     = false;
          bool   fVerifed     = System.Web.Security.FormsAuthentication.Authenticate(strUserName, strPassword);
          if( fVerifed)
          {
              System.Web.Security.FormsAuthentication.RedirectFromLoginPage(strUserName, fPersist);
