CS0103: The name 'Encoding' does not exist in the current context - asp.net

I have a webapplication running on framework 3.5 and is installed on multiple clients, working perfectly.
Except this one client... where all webservices that the application provide fail with the following error message:
Compilation Error Description: An error occurred during the
compilation of a resource required to service this request. Please
review the following specific error details and modify your source
code appropriately.
Compiler Error Message: CS0103: The name 'Encoding' does not exist in
the current context
Source Error:
Line 100: string EscapedFileName { Line 101: get { Line
102: return HttpUtility.UrlEncode(FileName, Encoding.UTF8);
Line 103: } Line 104: }
Source File:
c:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\DefaultWsdlHelpGenerator.aspx
Line: 102
Google points me toward the application might be targeting the client version of the framework or the system missing the system.web dll.
I've checked that both this possibilities are not the cause... Any ideas?

Try to use the namespace
using System.Text;

Check your web.config for any <clear /> elements for the namespaces.
Also, check your App Pool settings. If possible, can you create a new App Pool and try again?

I was able to fix this by locating the DefaultWsdlHelpGenerator.aspx file at the specified path and adding this to the Imports at the top:
<%# Import Namespace="System.Text" %>
In my case, I was also seeing a similar error about HtmlUtility not existing, which I was able to fix by adding:
<%# Import Namespace="System.Web" %>

Check your Page directive and make sure it is inheriting the proper file.
<%# Page Language="VB" AutoEventWireup="false" CodeFile="Index.aspx.vb" Inherits="Reports_Index" %>
And check the partial class too.
Partial Class Reports_Index
This typically happens if you renamed the file.
Check for other/additional dependencies which you might've missed. The last time I had this error it was because I only deployed the files which were part of my current build, instead of all of the files in my ./bin/ folder. I looked in my (currently working) dev machine, in the project/bin/ folder and found a few additional files (which were not in my newest build). Once I added those to my server, problem-solved.

The configuration section cannot contain a CDATA or text element

I am working on a vb.net web application project. And I was stucked by the following error. I believe there is not syntax with my web.config. Please help me.
Server Error in '/TSCA' Application.

I hads same issue, You should resolve in two simple steps.
1) verify by opening the URL of the Web Service in the Web browser and make sure it is properly responding. (IMPORTANT)
2) If step 1 turned out well, sure there are no typos in the web.config since (happened to me) what can happen is you have been a character "<" or ">" or misspelled most.

Could not load type 'NavigateWebApp.Global'

Recently we have moved our project to web app and everything is good but suddenly I do not know when I am trying to debug my application its showing me the following error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'NavigateWebApp.Global'.
Source Error:
Line 1: <%# Application Codebehind="Global.asax.cs" Inherits="NavigateWebApp.Global" Language="C#" %>
Source File: /global.asax Line: 1
--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:2.0.50727.4971; ASP.NET Version:2.0.50727.4971
I am sure that there are no build errors.
This is probably caused by your 'NavigateWebApp.Global' class/namespace not being available in the location you've specified.
Check where you define this and ensure it's accessible to the Global.asax page.
The root of the problem is your Global.asax file is referencing a class which no longer exists (or at least at the location you have specified). Simple fix is to update the Inherits attribute with the fully qualified path to your Global.asax class name (which you will find in the Global.asax.cs file).

Could not load inherited class for aspx page

When I transfer my project to a server, I now get this error message. What does it mean and how do I fix it?
Server Error in '/HD' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'HD._Default'.
Source Error:
Line 1: <%# Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="HD._Default" %>
Line 2:
Line 3: <%# Register Assembly="FormControls" Namespace="FormControls" TagPrefix="FC" %>
Source File: /helpdeskform/HD/default.aspx Line: 1
The #Page directive included this attribute: Inherits="HD._Default".
This means that there is a class _Default in the HD namespace associated with this page.
The error means that this class cannot be found.
A fix depends on how the site is setup and deployed:
You can solve this by copying the class to the correct location
Use the Visual Studio deployment tool (right click the web project then Deploy)
I prefer using the deployment tool - you can deploy to a local folder to ensure all dependencies are there, then upload to a server if you are not comfortable or able to use the direct to server options.

Configuration Error on custom config section -- could not find the file specified?

This has worked fine locally for months and just broke on deployment to the server (discountasp). I'm developing with .net 3.5 and asp.net mvc. I've previously successfully hosted asp.net mvc applications on this same account (but without the config section).
I have a custom config section set up in my web.config file that's causing the following error on load:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: An error occurred creating the configuration section handler for SCConfig: The system cannot find the file specified.
Source Error:

Source File: E:\web\irstagelert\htdocs\web.config Line: 180
Version Information: Microsoft .NET Framework Version:2.0.50727.3074; ASP.NET Version:2.0.50727.3074
The part of the web.config where I define the config handler is:
<section name="SCConfig" type="com.lerteco.SoxCompliance.ConfigHandler.CustomTagHandler, com.lerteco.SoxCompliance.ConfigHandler"/>
I've played with a few different iterations of the type, but they all produce the same error message as above.
The top of the class file is:
namespace com.lerteco.SoxCompliance.ConfigHandler
{
[Flags]
public enum GroupCodes
{
....
}
public class CustomTagHandler : IConfigurationSectionHandler
{
public object Create(object parent, object configContext, XmlNode section)
{
And I've confirmed that on the host the /bin/ directory contains both the com.lerteco.SoxCompliance.ConfigHandler.dll and ....pdb files.
Thanks for any help,
James
Jacob was right; it wasn't the handler file itself, but an error being generated from within the handler.
I ended up writing code and moving around return statements until I found the problem.
Specifically, I created an RSACrytpoServiceProvider() and got the error detailed in this posting RSACryptoServiceProvider CryptographicException System Cannot Find the File Specified under ASP.NET .
