Why won't Visual Studio break on this unhandled exception? - asp.net-mvc-3

When submitting a form, a Yellow Screen of Death appeared even while in Debug mode in Visual Studio. The problem I had is solved, it was a missing resource value, but I'm interested in why I'm not able to break on the exception.
I tried the following, but nothing changed the situation:
Stepping through the code.
Changing the Debug -> Exceptions settings.
Checking Enable .NET Framework source stepping and Enable source server support.
How can such an exception be caught, or why is it not possible to catch it?

It is not possible to break on this exception, because Microsoft's public Symbol Server does not provide source code for everything.
Adding a breakpoint via the dialog to System.ComponentModel.DataAnnotations.ValidationContext.set_DisplayName will break, but Visual Studio will say that there is no source code available.

Looks like you have some dataAnnotationAttribute for model field, so asp.net takes care about it - before your request fires breakpoint in controller

What kind of Dynamics CRM 2011 Online authentication needs to use deploy in godaddy shared server

I am having an issue when I tried to deploy an application which communicates with Dynamics CRM 2011 online in godaddy shared server.
I don't have any issue when I run in my local, I am using wsdlbaseproxies online code provided in sdk\samplecode\cs\wsdlbasedproxies\online to authenticate the dynamics CRM. This process is creating LiveDeviceID.xml in the local system and failing to create the same in the godaddy shared hosting server.
This application is developed in .net which captures leads, opportunity and saves/retrieves the same in/from CRM 2011 online.
I really appreciate your help and input on this.

Issue with System.Web.WebPages after installing MVC4

I have installed MVC4 and an MVC3 app that I have is now causing me problems. I get the error :

However, I cannot find any references in my code to v2 of WebPages, and I am wondering why I am getting this error. Can anybody help?

Security Exception with medium trust, ninject and entity framework

I keep getting this exception whenever I try running my project in medium trust. The project is MVC Forum, and even though I don't need to run any of my own sites in medium trust, I figure I better make it work in the medium trust environment anyway.
I'm using Ninject for DI (the DLL that works in medium trust), and that works - the MVC controllers are loaded with constructor injection as expected.
The "funny" thing is that the method (in my code) that fails, take 2 arguments, these are both loaded from the database using entity framework, so I have no idea why this fails, when entity framework clearly already work in other parts of the code.
What is the reason behind this exception? It's like looking for the famous needle in a haystack.

Small update, I'm using code first. Thanks for looking!
This looks like the exception you get if your entity classes contain properties that are not public--i.e. they are internal, protected, or private. EF5 and below only support mapping to public properties when running in a partial trust environment.

This could be related to table in which I duplicated a foreign key. It was called something like myKeyId, and I now have myKey1Id and myKey2Id in that table. I checked everywhere in my code, and I can't find myKeyId anymore.
The error message is so generic that I don't know how to pin-point what is causing this error. Any advice would be welcome.
I hade the same error.
I did clean solution rebuilt and it worked.
My solution was to turn off IIS and then start VS project again.
I ran into this error today, too.
It turned out, that my data model has missing the foreign and primary key constraints in the data base.
I had copied the original database to a local database to speed up the execution, but I had only copied the data and not the relationships.
Other errors i had in this context were
an item with the same key has already been added
and
Unable to update the EntitySet Table because it has a DefiningQuery and no InsertFunction element exists in the ModificationFunctionMapping element to support the current operation
it all was due to a faultive database structure
Ran into this issue today. I deleted all of my tables from the Entity Model .edmx file, the updated my model from the Database (right-click --> update from database).
Then I re-compiled and it ran fine. Such an odd error.
I am running MVC 4 and EF 5.0
