WebMarkupMin Inheritance security rules violated while overriding member

Question

I'm using webmarkupmin library to minimize the html output of a asp.net site. The problem is that when I publish in godaddy hosting I get the following error:

Inheritance security rules violated while overriding member: 'WebMarkupMin.Core.CodeProcessingException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

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. 

Exception Details: System.TypeLoadException: Inheritance security rules violated while overriding member: 'WebMarkupMin.Core.CodeProcessingException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

I've read that I could add this line [assembly: SecurityRules(SecurityRuleSet.Level1)] to the assambly, but I don't have the source code of WebMarkupMin to modify it and make it work so question here is, do you have any idea how to fix it?

Thanks!

Just added a full trust tag in web.config

    <trust level="Full" />
