[Solved] Html.Telerik().StyleSheetRegistrar().StyleSheets Security Exception on Medium Trust

[cheburek]

Hi. I found that Telerik StyleSheetRegistrar and ScriptRegistrar work fine while application is in Full trust environment. In Medium trust mode
following piece of code:

Html.Telerik()
    .StyleSheetRegistrar()
    .StyleSheets( group => group
                 .AddGroup( "custom", g => g.Enabled( true ) ) );

(the same also with ScriptRegistrar)

throws exception:
 ========================================
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Is there a way to work with these telerik mvc controls under Medium trust environment?
Any help would be appriciate. Thanks.

P.S. This issue seems also related to other controls from Telerik MVC package. At least I tried Grid and it also throws the same exception.
I do use .NET3.5SP1, VS2010, MVC2.0, Telerik MVC 2010 Q2

Hello cheburek,

 I tried to reproduce this with a more recent version but everything worked fine in medium trust. Do you use a modified policy file? I am sending my test project as attachment.
