Exception Problem when publishing ASP.NET Web Application - asp.net

I have a web application and when I decided to test on IIS 7 i have this Exception when trying to load a couple of pages that uses Entity Framework 4. I use EF 4 with my own CRUD assemblies but sometimes using the EntityDataSource. I have noticed that the problem is not appearing in all my Web Pages but I think in those that I use the EntityDataSource.
Here's the log from a Page:

I think its the EDM problem but I can't get through.
I should mention that in my development pc is working all perfectly!!!
My controls are DevExpress but I dont think this should play any role!
Thank you.
[EDIT]
Thank you RD for edit.
Forgot to mention that I use Self tracking Template with the Entities.tt in a separate assembly!
[EDIT 2]
On my local Windows 7 IIS works OK! It's Windows Server 2008 I can't get it done!

This was an error as it seems that assemblies are not loaded. The app needed assemblies that I dont use into my application but I guess it searches using reflection. This had to do with DevExpress assemblies that I guess are referenced or loaded from reflection in another DevExpress assembly. The solution is to Log the LoaderExceptions and see what assembly u need.

How to change page assembly in ASP.Net 2.0

I want to change one page on my ASP.Net 2.0/.Net 3.5SP1 application. The application is running on IIS6/Windows 2003. The application is precompiled so each page is composed of a ASPX file, a .compiled file, and a separate DLL assembly. These are mysite/olt2.aspx, mysite/bin/olt2.aspx.cdcab7d2.compiled, and mysite/bin/App_Web_ekkmrelo.dll. Note: the path has been changed for security reasons. The .compiled file appears to be the linkage between the olt2.aspx file and assembly.
The contents of the ASPX file, and .compiled file:
[Olt2.aspx]
This is a marker file generated by the precompilation tool, and should not be deleted!
[olt2.aspx.cdcab7d2.compiled]
<?xml version="1.0" encoding="utf-8"?>
<preserve resultType="3" virtualPath="/mysite/OLT2.aspx" hash="617d394d4"
filehash="432defb6ed3bc6fc" flags="100000" assembly="App_Web_ekkmrelo"
type="ASP.olt2_aspx">
<filedeps>
<filedep name="/mysite/OLT2.aspx" />
<filedep name="/mysite/OLT2.aspx.cs" />
</filedeps>
</preserve>
I compiled a new page in my development environment and it produced a new assembly and .compiled file. The only changes to the new version of olt2.aspx are alterations to JavaScript. The new .compiled file:
[olt2.aspx.cdcab7d2.compiled]
<?xml version="1.0" encoding="utf-8"?>
<preserve resultType="3" virtualPath="/mysite/OLT2.aspx" hash="617d394d4"
filehash="435cf6a2206e330f" flags="100000" assembly="App_Web_n1jva4in" type="ASP.olt2_aspx">
<filedeps>
<filedep name="/mysite/OLT2.aspx" />
<filedep name="/mysite/OLT2.aspx.cs" />
</filedeps>
</preserve>
I added the new assembly "App_Web_n1jva4in.DLL" to the bin folder, and replaced olt2.aspx.cdcab7d2.compiled with the new version. The security on the newly added DLL matches other DLL in the bin folder. But when I attempt to open OLT2.aspx I get an error (see below). I have tried stopping the application pool, deleting the temp asp files. If I replace olt2.aspx.cdcab7d2.compiled with the original version, the page loads.

My questions
Is there a reason why this cannot be done? Is there a way to make this work, or pinpoint the problem?
While writing up the question for stackoverflow, I wondered if there were some dependencies in the new assembly that had changed. To answer that, I used ILSpy http://ilspy.net and sure enough there were references to these assemblies: App_Web_wlaluoz4.dll and App_Web_mkzxmd4c.dll. I copied those two assemblies into the bin folder. Using ILSpy, I checked that the newly added assemblies did not have other dependencies, and fortunately they did not.
The new version of Olt2.aspx page worked!

Having trouble reading a value from View.ascx.resx from code behind

I have the following files: View.ascx, View.ascx.cs, View.ascx.resx . In the file View.ascx.resx, I'm have a lot of trouble reading the value for the key EmailAddress.Text from my code behind.
I tried this:
object keyValue = System.Web.HttpContext.GetLocalResourceObject("~/View.aspx", "EmailAddress", culture);
EmailAddress.Attributes["placeholder"] = keyValue.ToString();
And it gave me the error:
Error: Contact is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: The resource class for this page was not found. Please check if the resource file exists and try again. ---> System.InvalidOperationException: The resource class for this page was not found.

I tried this:
ResourceManager rm = new ResourceManager("items", System.Reflection.Assembly.GetExecutingAssembly());
String r = rm.GetString("EmailAddress");
And it gave me this error:

Make sure "items.resources" was correctly embedded or linked into assembly "Contact" at compile time, or that all the satellite assemblies required are loadable and fully signed. ---> System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture or the neutral culture.

I tried several other example from the asp.net code library, but kept getting other errors. How do I grab a value from the View.ascx.resx file?
Ok finally figured it out. I have to use the DotNetNuke API because this is a DotNetNuke project.
String s = DotNetNuke.Services.Localization.Localization.GetString("EmailAddress",this.LocalResourceFile);

An item with the same key has already been added. After switching web hosts

I'm transferring a .NET Framework 4.0 site from 1 web host to another. The site on the existing hosting seems to be working as intended. However, after transferring the site files and database to the new hosting and then fixing the web.config connection string to point to the new db, I'm getting errors when trying to access a page that pulls from the database.
I did not write the site, but it appears to be using a code-first setup.
Server Error in '/' Application.
An item with the same key has already been added.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I've tried rebuilding the edmx file from the new database server after transferring the files. I know my connection string is working because I wrote a small test that connects to the database through the same connection string and it is able to retrieve data.
The only change I've made to the code base after copying it from it's working state is to the web.config's db connection string.
The only real notable difference from the old hosting versus the new hosting is that the old hosting was using SQLEXPRESS(unknown version), whereas the new hosting is using MSSQL 2008.

Error with SQLXMLCommand and Deployment to IIS 6.0

I am getting an error when trying to move my ASP.NET application from VS2010 to our IIS 6.0 webserver. The error happens on the first time the app tries to make a new SQLXMLCommand Object on the login page.
When navigating to the login page and entering valid credentials I got an error saying a null reference exception was thrown. Investigating into the exception we were able to determine another exception was being thrown and caught, causing the null reference exception later in the code.
The Corresponding line of code throwing the exception:
New SqlXmlCommand(conn.ConnectionString & ";Provider=SQLOLEDB.1;")
The exception causing the problems below:
Retrieving the COM class factory for component with CLSID {83D0FC3E-8B31-4B35-A1B2-346BA3954514} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."

Looking further into the problem, the exception is only thrown on the Web Server. No exception is thrown if I am using localhost. I though I may be missing a reference to Microsoft.Data.SqlXml.dll as it was working localhost and not on the webserver. I tried fixing this by included the dll reference in my deployment project and making sure it was added to the bin folder, but with no avail.
Thanks, for the help.
Edit:
SQLXML 4.0 was not installed on our webserver, it was part of the baseline installation of my machine.
In addition to the managed SQLXML assembly, you need to install the native SQLXML library on the server.
The SQLXML libraries are documented at http://msdn.microsoft.com/en-us/library/ms171779.aspx, and you can find the installer at https://www.microsoft.com/en-us/download/details.aspx?id=30403

ASP.NET UnauthorizedAccessException when accessing item from cache

We have some code that occasionally flushed out certain keys in the ASP.NET cache in order to make sure that we are getting up to date data from our Dynamics CRM system. It seems to work fine most of the time, however we are getting intermittent exceptions on page reloads that I suspect is related to this forced cache flushing.
Here is the error in the UnauthorizedAccessException:
Access to the path 'appDomain=/LM/W3SVC/1/ROOT-1-129326029589946795:key=Microsoft.Xrm.Client.Services.InMemoryCrmCacheProvider:Crm:Query=953227368' is denied.
In case it is helpful, here is how I am flushing the cache items:
private void Flush()
{
IDictionaryEnumerator cacheEnum = this.HttpContext.Cache.GetEnumerator();
while (cacheEnum.MoveNext())
{
var key = cacheEnum.Key.ToString();
if (key.StartsWith("Microsoft.Xrm.Client.Services.InMemoryCrmCacheProvider:Crm:Query"))
System.Web.HttpContext.Current.Cache.Remove(key);
}
}
My questions:
Is there some level of permission required to access or remove cache items? I googled this but did not find anything specific (even in MSDN).
Have you seen this error before? How did you resolve it?
UPDATE: here is the stacktrace.

UPDATE2:
We just updated to the 4.0.13 version of the SDK in order to turn off caching (actually I could only get it to work by setting the duration to 1 second, see below). This allows us to get around the issue of CRM needing to be flushed, but we are still getting the caching errors in our environment, although they look a little different now:
Message=Access to the path 'appDomain=/LM/W3SVC/1/ROOT-1-129341239247458264:key=Microsoft.Xrm.Client.Services.InMemoryCrmCacheProvider:Crm:User=00000000-0000-0000-0000-000000000000,00000000-0000-0000-0000-000000000000:Query=923237368' is denied.
Data=System.Collections.ListDictionaryInternal
For what is is worth, the context configuration I am using is below. I am adding a bounty to this question as a last ditch attempt.
<microsoft.xrm.client>
<contexts default="Crm">
<add name="Crm" type="CRM.XrmDataContext" serviceName="Default" />
</contexts>
<services default="Default">
<add name="Default" cacheProviderName="Default" />
</services>
<cache defaultProvider="Default">
<providers>
<add name="Default"
type="Microsoft.Xrm.Client.Caching.InMemoryCacheProvider, Microsoft.Xrm.Client" duration="00:00:01" />
</providers>
</cache>
</microsoft.xrm.client>
We finally figured out the answer to this issue. The problem was related to impersonation (we had it turned on in the web.config) and the fact that we were accessing XRM using a singleton. Apparently, when multiple users tried to run simultaneous CRM queries through our software, the singleton would make the connection to CRM under their user context. Apparently while this is happening, the cache for the query results are "owned" by that user context. When another user tried to run a query at the same time, they would receive a 401 status code.
The fix ended up being to turn of impersonation and do some minor refactoring so that we did not need it anymore. I imagine we could instead have allowed multiple CRM instances--though we intentionally don't do that for performance reasons.
I hope this helps anyone else who might be seeing these funky errors.
I can't imagine that the exception is actually tied to the Cache.Remove call.
Just a guess, but is it possible that the exception is related to the CacheItemRemovedCallback and not the actual removal step (not sure if the call-back is executed synchronously on the same thread)?
Can you post the full stack trace for the exception?
