Is XmlTextReader marked with HPA

Hi all,

I want to know if the System.Xml.XmlTextReader is marked with Host Protection Attributes(HPA) in the SQL Server 2005 CLR. I ask this because when I add a custom class that inherits from System.Xml.XmlTextReader, I get a code access security error at runtime. I am able to register the assembly just fine. I have tested it with all the cases and pretty much sure my code breaks in this class.

My code snippet is shown below:

public class CustomXmlTextReader : XmlTextReader
{
......
......
}

Doesn't really matter what is in this class. It gives an expection even when there is no code inside.

Any help is greatly appreciated.

Thanks,
Jai
