Error on IntelliTrace

[Nelson]

Hi ..

Searched the forum, however I found nothing about my problem.

When trying to run a web service on my local machine, the problem does not happen. When you run the deploy server the following error occurs:

Telerik.OpenAccess.Runtime --> System.TypeInitializationException: The type initializer for 'OpenAccessRuntime.Intellitrace' threw an exception. ---> System.Security.SecurityException: Request failed.

I tried to look for something that disable IntelliTrace, but as far as I saw it only runs within visual studio (2010 or 2012).

As far as I know my ISP's server runs on medium trust.

Does someone could help me?

Regards.

Hello Nelson,

In order for Telerik OpenAccess ORM to work properly we need at least a Medium Trust and in general security exceptions like this one are thrown if we do not have the required trust level. In order to configure OpenAccess ORM to work on medium trust you could follow this article for our domain model approach or this one for the code only scenario.

However please bear in mind that if you are not using the latest official version of OpenAccess ORM - Q3 2013 SP1 (version 2013.3 1211) you could get the security exception even in medium trust because of an issue which is already fixed in this version.

Could you please confirm that you are using the latest available OpenAccess ORM version and have both your model and server are configured for a medium trust?

I am looking forward to your feedback.

Hi Dimitar

I checked the version I had and was not really updated. I was a previous version of the one you entered.

Seems to have solved the problem. But now I have another related to MySql.Data.

Because my ISP using the "Medium Trust" seems to lack an allowable use in class System.Net.Socket configured within web_mediumtrust.config for it to work.

But that's their problem. I'll check with them and if I have anything else related to this issue I will contact you again.

Anyway thanks for the help.

And congratulations for the work with OpenAccess. It's a great tool!

Hi Dimitar ...

I talked to my ISP and they told me it is not a common problem.

If we direct access to MySql without the OpenAccess works normally.

Follows the error that occurs this time.

Hello Nelson,

 Can you provide the inner exception of this exception?  That would provide more information on the exact call that causes the exception.

Hi Ady ...

As the problem occurs on my ISP, I can not pass the actual Exception that occurs. What I have is the stack trace of the problem:

Telerik.OpenAccess.Runtime --> Cannot perform CAS Asserts in Security Transparent methodsem:
   at OpenAccessRuntime.ExceptionWrapper.Throw()
   at OpenAccessRuntime.Helper.getPersistenceManagerFactory(PropertySet props)
   at OpenAccessRuntime.DatabaseAdapter.AssertPersistenceManagerFactory(String usr, String password, Boolean open)
   at OpenAccessRuntime.DatabaseAdapter.GetObjectScope(TransactionProvider provider)
   at Telerik.OpenAccess.Database.GetObjectScope(TransactionProvider provider)
   at Telerik.OpenAccess.OpenAccessContextBase.GetScope()

MySql.Data --> Cannot perform CAS Asserts in Security Transparent methodsem:
   at MySql.Data.MySqlClient.MySqlClientFactory..cctor()

The all indications, it looks like something is when I try to call the following method of the class that represents the object context:

public IQueryable<Clientes> Clientes
{
    get
    {
        return this.GetAll<Clientes>();
    }
}

Thanks for your attention.

Hello Nelson,

 This seems to be the same problem which you mentioned in the ticket - 706893.
Can you try to install a version lower than 6.6.5 and try again?

Hi Ady...

Sorry for long delay in answer, but I having to working out these days and dont have time to do the adjustments.

Really the change for a old version solve the problem. I have used the version 6.3.5 that is provided by my ISP.

For that someone have the same problem, the solution work perfectly!

On my opinion the unique problem is that he have do use a version that is old and can be have bugs on it.

Is there any plan to update de OpenAccess to use a new version of mysql connector without the problem of medium trust?

Thanks.

Hello Nelson,

 As mentioned in ticket 706893 there are no immediate plans to upgrade OpenAccess to the latest MySql connector. Maybe you can close this ticket so that we maintain a single thread for communicating on this subject.
