Is it this Host Protection that is blocking my Trace.Writes to not cross boundaries like System account to logged in user account?

The CLR doesn't provide a general mechanism to disable host protection (otherwise the hosts wouldn't be too happy :-) ). Individual hosts may have a way to do so, but in general that won't be possible.

Shawn,

I am creating a Custom Data Extension for SSRS over our data access layer which uses nHibernate. I am getting the 'Attempted to perform an operation that was forbidden by the CLR host' error.

Is there anyway I can disable the CLR Host Protection for my Custom Data Extension.

Thanks in advance,

Amitabh

Stephen,

Could you setup a static Dictionary<int, string> to enable this scenario?

Hi,

I am working on runtime for a language vendor and I have a question for you!

Q. If you have an assembly that has a loose contract between two static methods and you need to pass information between but without using "this" or as a parameter how can you do this? But still want the assembly to be SQLCLR SAFE.

For example:

private static readonly LocalDataStoreSlot localSlot;
static SQLSUB()
{
localSlot = Thread.AllocateDataSlot();
}

private static string GetMessage()
{
return Thread.GetData(localSlot).ToString() +" from HelloSub";
}

public static string Message()
{
Thread.SetData(localSlot, "Hello");
return GetMessage()+" [CS]";
}

This example will fail in the class constructor with a HostProtection exception (requires: SharedState, ExternalThreading permissions). The use of [ThreadStatic] does not help because the attribute is not permitted and it also applies to “static field”.

What options do I have?
