ASP.NET runtime error: Length can not be less than zero. Parameter name: length

Question

I am using visual studio 2008 on vista business. We just recently upgraded from xp. Now when I open a web project I get this error

ASP.NET runtime error: Length can not be less than zero. Parameter name: length<

in every .aspx file on this line of code:

<%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="ContactNotes.aspx.cs" Inherits="ContactNotes" Title="Contact Note" %>

This started happening after new install, anyone have any ideas on why this is happening?

Answer 1

are you parsing empty string?

Answer 2

Sounds like a Web.config issue. I remember getting this error when in the ASP.NET membership provider section, we had a constraint on the minimum password length, or something like that. This resulted in that error. Look for something similar. I know this is rather vague, but perhaps it'll steer you in the right direction.
