.net - System.Web.HttpException Could Not Load Type '[namespace]?
Feb 7, 2011
This started as Could not load type 'Global' error. After I tried a few things and getting no where I deleted the Global.asax file and now the error is Could not load type '[namespace].???'Where ??? is the class name of every page I try to load.The web site (when executed within VS2008, local dev computer) works fine but once published (with no errors) and deployed to the server gives me Could not load type '[namespace].???' error
I did install elmah and I was able to get more details for this "generic" Could not load type '[namespace].???' error
elmah reports a HTTP error 500 :
System.Web.HttpException Could not load type '[namespace].???' ->
System.Web.HttpParseException: Could not load type '[namespace].???'
I have checked the "basics"
References
Doing a clean and a build Checking the Inherits attr in the HTML against the code behind
UPDATE #1 I did deploy the site to a different DEV computer (configured IIS, virtual folder, etc.) and it works. When I use the same published code on the server, get the generic Could not load type '[namespace].???' error
UPDATE #2 I created a test web app. One form (Default.aspx) with a button. The click event does a Response.Write("Hello World"); I moved this app to the server and guess what, I get the Could not load type TestSite._Default
UPDATE #3 According to the fusion log viewer, these two websites are attempting to load CppCodeProvider and VJSharpCodeProvider, but I have no references to any of these. After a Google search, I found this post.I checked and I have no references to JAVA files.

I am using VIsual Studio 2008 , framework 3.5 but i don't know why in error information version is showing 2.0
i install tool kit according 3.5 framework.also note, framework built-in ajax tags i can use fine and they work properly.
i have installed ajaxtoolkit 3.5 but when i debug i am getting this error Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' even i have changed my tags to
I have an ASP.NET 3.5 website application using C# and SQL 2005 running on a web server. Now the application has the ability to create new aspx pages with content and the relative aspx.cs and design.cs pages needed on the fly and store them in the base directory on the server. Think of it as a crued Visual Studio website on the server for admin to click a few options on a page then the new pages are created for them without the need of a web developer. This all works fine and the code is working 100% (for the moment).
My problem now is the following: When i now navigate to this newly created page i get the following error - Parse Error : Could not load type 'Namespace.PageName'
I've looked into the reasoning and microsoft say "These errors occur if the .aspx page contains a reference to a code-behind module and if the application has not been built." Which now makes sense the application does not realise that these new pages are part of its system even though i can navigate to them.How do i get the system to recognise these new pages and rebuild itself accordingly?Now i cannot rebuild the system localy then reupload to the server, this needs to be accomplished on the server by the system, because the site cannot afford to have down time everytime admin decide to add new pages.
when I put a break point i get this error message:
Error 1 The type or namespace name 'X509Certificate' could not be found (are you missing a using directive or an assembly reference?) D:UsersatttDesktop fre etetrtDefault.aspx.cs 7 53 D:...attt
I just deployed a test MVC2 application to a shared host and get the error Could not load type 'System.Web.Mvc.UrlParameter' when firing up the application.This is a bin readable application as my hosting provider does not yet have MVC2 installed, however, they assure me this should run OK. Also this is a barebones application, basically the default project structure published for testing purposes.Any suggestions as to resolving this?
I am using Toolkit ScriptManager and Accordion and am getting this error.Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
I was earlier having a problem with referencing a 3rd Party Dll (Here) but have overcome this problem and am now having a problem referencing my own classes!
Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation
Error:Compiler Error Message: CS0234: The type or namespace name 'Secure' does not exist in the namespace 'source_extranet' (are you missing an assembly reference?)
The line that the Error points to this line in the class:
source_extranet.Secure.BackendCustomData newdata = new source_extranet.Secure.BackendCustomData();
This line of code points to a class in the same folder as the calling code class.
However when I build I get an error stating- Could not load type 'MyNamespace.Global'.
This seems to be because the MyNamespace namespace (defined in the code behind file Global.asax.cs) is not seen by the compiler in the Global.asax file (does not show in R# intellisence..).This turned out to be a very hard nut to crack...
Note: The Global.asax and the Global.asax.cs are located in the same folder.
Note2: When compiling from the vs prompt with csc it compiles o.k.

I have a website(connect to active directory and pull the required details) deployed on the production web server and it is working fine from last one year.
But from last two days users are getting the following error frequently and find the error details below:-
how i can proceed on this error so that i will apply the fix in the webserver.
I ran into this error today and much googling didn't get me the answer. I have been for years now publishing this particular site by simply doing "Publish web site" and then supplying it a UNC path, then I go to the server delete the old bin and copy to the new bin folder to the live site, this has always worked except today I started getting the "cannot be requested" error for certian pages in certain directories. Everything else worked and after several attempts nothing else broke and only these same certain few pages where screwed up - there was nothing exciting about any of these pages, in fact they were part of the admin portion of the site and were very simple
