未知服务器标签ASP.NET 2.0 Visual Studio 2010

Question

I am in the process of upgrading a website from Visual Studio 2005 to 2010. I ran it through the importer, however I'm having some errors. Specifically I'm having the following error:

Error   615 Unknown server tag 'CTL:PayPal'

If I go to the file that it is complaining about I have the following at the top of the file:

<%@ Control Language="C#" AutoEventWireup="true" Inherits="PowerShop.Admin.UI.Customer.Controls.CustomerPaymentList" %>
<%@ Register TagPrefix="CTL" TagName="OrderPaymentList" Src="~/Order/Controls/OrderPaymentList.ascx" %>
<%@ Register TagPrefix="CTL" TagName="PayPal" Src="~/Order/Controls/OrderWizard/PayPalDetail.ascx" %>
<%@ Register TagPrefix="CTL" TagName="Term" Src="~/Order/Controls/OrderWizard/LineOfCreditDetail.ascx" %>
<%@ Register TagPrefix="Shipping" TagName="AddressVerification" Src="~/Controls/AddressVerificaton.ascx" %>
<%@ Import Namespace="PowerShop.Configuration" %>

I have checked and double checked the register tags and the file but everythin appears to be correct. The file exists (PayPalDetail.ascx) in the exact location I am specifying. This page does not throw any errors on any of the other register tags. Any help or insight would be much appreciated.

I think it would be in wrong place like you could have by mistake put it in the page instead of putting it in the UserControl which have the Register tag.

Also, this can occur if the Paypal user control is not able to compile due to some bug in it.

Where are you placing the CTL:Paypal tag ??
